First GoCart ----- Oh Yeah!!!
With a very big grin on my face I'm excited to announce that today I was able to take #8690, Factory Five Roadster 20th Anniversary #008 out for it's first drive. After spending about 20 minutes adjusting the timing and idle to get it where I wanted for now, I started the video below. This was from my GoPro that I've used many times in both my son's and my own race cars with no problem. But today I had a minor one. I guess it was rattling inside the case so the audio is picking up that, but it also picked up issue #1 that I have. The U-Joints/Pinion angle, more on this in a moment. So enjoy the short ride, I did not go any further after I realized that the U-joints were not happy. But I did not park it until I goosed it just a little...
As I say in the video, I can just feel the power wanting to be unleashed. I'm going to take a couple day break from the build, catch up on some household chores and then get back to it this weekend. All I can say right now is WOW! That was a fun, short, but very fun little drive.
So a Question.
- The Drive shaft has a significant angle going from the transmission and then angling up to the pinion. (2015 IRS) I need to put some spacers in the trans mount and raise up the tail... Where is the best place for the spacers? Under the "A" frame or between the "A" frame and the trans mount? Perhaps between the trans mount and trans? Just curious your thoughts. I was planning to pick up some Grade 8 Washers and get that drive shaft angle much closer to where it needs to be this weekend.

Minor Tweeks and Back to the Beginning
Today was a day of minor tweaks and getting back to the beginning... drilling and clekos...
Before really getting started, I found that after my short go cart drive that my DS camber was way off so I adjusted that to a much better look. Then rearranged the garage, cleaned things up a bit and put the car up on the jack stands. Removed the side pipes to get them out of the way and then started out by addressing the loose drive shaft to pinion flange. Removed all 4 bolts and cut off about 3/16" on each one. Cleaned them up on the wire wheel, and reinstalled, loctite and torqued appropriately. The flange is tight now...
Continued in that area by pulling out the bottom bolts from the trans mount and raising the transmission tail up about 3/4" to fix the pinion angle. Things are much better now. I used a stack of thick washers and some new 1.5" grade 8 bolts to replace the .75" long bolts that came out. Torqued them down on the lock washers and call this job complete.
Took a long brake and caught up with a very good friend for lunch and stopped by the DMV to pick up some forms to start the title/registration process. I'll cover this process for SC in a separate thread for others to have available. Looks like it is going to be very straight forward and smooth.
Back to the build after the DMV I decided I need to start looking at getting ready to drop the body on. I had not completed any of the panel drilling for the driver's foot box top and side. So I went back to the beginning and broke out the 1/8" drill bit and clekos... Also installed some nutserts on the top access panel and then pulled them all back off as I still need to do some work in the DS foot box before they go on permanently.

Working on small items.... pt1
Today was kind of an easy day. I worked on several small items, time consuming items that have to get done...
1st, Installed the horns. Fairly simple job, followed the build manual almost, just a couple minor adjustments to that guide. First off, I did not mount them with the brackets together. I actually put a little separation between the horns so that they looked a little less cramped in the space. I used 1/4-20 stainless bolts, self locking nuts and washers. I also put red loctite between the 3/4" tube and the silver horn brackets to "glue" them in place and hopefully prevent them from moving. Oh, and in my garage, the horns are extremely loud.

Next I pulled out all of the hood hinge parts and some other bare metal parts. Spent a couple hours massaging the sharp edges off of all of them, getting the plasma cut nibs off of them and rounding off all the sharp edges. I used my 4 1/2 side grinder with at 60 grit flap wheel. Then cleaned them all with paint thinner and hung them up. Sprayed them all with a couple coats of self-etching primer and then a couple coats of final paint. I'm using Dupli-color paint that is a near perfect match to the 20th Anniversary frame power coat gray color. Those parts will be put away and be ready for use when the time comes.

I also installed the trans tunnel cover shifter fill plate. Nothing special here except as you can see there are two rivets missing... Those will actually be into the 3/4" cross tube underneath if I do in fact permanently attache that cover. I'm thinking of using industrial strength hook and loop (velcro) to attache it and if I do, then I'll just put the rivets in and flatten them with a few taps of a hammer.

Next... I completed the door latch improvements in preparation to using them.

Working on small items.... pt2 Door Latch Modification
I followed a couple different leads on the modification/improvements on the door latches. While I've seen where some never had a problem with the latches and others that have had several problems, I wanted to do what I can now to prevent any problems in the future. So, this is what I did.
One of the issues I've read about is that the small ball shaped handle that is only pressed into the latch bar will come off. I started by drilling a 5/8" hole into my 2x6 board that I use for just about all my drilling on my work bench. This was so that the knob would be able to be held in place as I used a center punch and drill on it. Center punched the end of the knob on the back of the lever and then using a #62 drill bit, drilled a hole about 1/2 inch deep. Then, tapped it with a 6-32 tap and cleaned out the oil I used during the taping with some carb cleaner. (want the loctite to work well) I installed a 1/2" 6-32 cap screw with washer, both stainless steel and I used blue loctite. Clean, simple and a little insurance keeping the latch knob in place.

Next I opened up the latch by removing the two small screws that hold the chrome cover in place.
next, I picked up a couple 5/16 stainless steel carriage bolts, and self locking nuts. Using my bench grinder, I flattened the top of the carriage bolt rounded head to basically make them flat to fit when installed. I used one of my extra self locking nuts to hold the bolt with vice grips as I did the grinding. It gets very hot so the self locking vinyl actually gets pretty soft and renders the nut unusable for anything except this type of use. The square in the door latch itself seems to have a very slight taper so it was necessary to use a file to "clean" out the square so that the shank of the carriage bolt could sit flat in place. This was very minor filing, not really opening the square hole, rather just cleaning it up.

Next I found a couple spacers that were not used from my brake install that were just the right thickness and almost the perfect inside diameter to sit down over the latch. I used a step drill to open up the first half of the spacer so that it set perfectly over the top of the latch collar. Place a stainless washer over the top of that and tightened down the self locking nut.

I use white lithium grease on all moving parts and then open and closed, in and out, over and over the latch to be sure that grease had a chance to get into all the moving parts. The latch feels very smooth and much easier than the original feel. Cleaned and polished the latches and put them back into the plastic bags and the box. Ready for use when the time is right.

Body Is Down on Chassis - NOW What????
Ok so today I rearranged the garage and dropped the body down on to the chassis. I have two bolts going into the rear QJ mount holes, not tight, just holding it up. Then it is pushed all the way forward and down over the front QJ mounts. The door sills are up flush under the chassis. I've put several folded up shop rags in strategic places to simulate the bulb seal holding it up slightly. The body is just at the door strikers as I see in Jeff K's instructions is a good starting point.
So my initial observations of problems is that the the body is sitting on my tach and one of my switches. I'm thinking I will need to cut a bit off of the roll over the dash. Also the cutouts for the headers seem to be way off. I will say that I have two different sets of headers and both seem to be in the exact same position. When I had the side pipes on, they seemed to line up with the chassis very well so I'm kind of at a loss as to why the cut outs are so far off.
The hood opening, both sides are sitting right down on the 3/4" tubes and seem to be centered on them.
THIS IS WHERE I'VE DREADED going on this build. What do I need to do and where do I start?
