33 Hot Rod Windshield install with heater/defroster
While attempting to install my windshield today I ran into a problem that is caused when having a defroster installed. They say at the end of installing the windshield that if you have a defroster to cut the vent holes now. Well you can't use a air saw to make the cut with the windshield installed. So I went about installing the defroster first. I measured, cut, and installed the complete defroster and defroster duct work. This is where I ran into a problem. With the defroster duct installed the center bolt for the windshield strikes the defroster duct. I could not find anything in the manual or the defroster instructions telling me to avoid the problem. So I had to uninstall the defroster duct work to get the windshield to sit flush with the dash again.
The problem is simple to correct. Two solutions. Cut the center bolt before installing it into the base of the windshield (don't cut the hex end) just long enough that it can take the 10mm nut and washer but not longer or get a 6mm button head screw about 1" long and insert it from underneath before installing the defroster duct. I am going to try the second choice. I will let you know after I finished what the length turned out to be.
UPDATE: I used a 6mm pan head bolt 3/4" long. I had to tighten the bolts on either side to "flex" the body so the bolt would catch some threads. Worked fine. Defroster is installed and functional.
Here are some pictures of my progress:

I made a template out of the flap of the windshield box. I pushed it up against the bolts to get my location. It wasn't exact. I had to widen a few to allow the windshield to fit.
