I purchased my 33 built and my battery is under the car. I feel I need to install some form of external battery jumper post in the trunk; since getting under the car every time I need a jump would be convenient. Does anyone have a suggestion. Thanks.
These are popular with drag racers: https://www.summitracing.com/search/part-type/remote-battery-jumper-terminals
But I use a more discrete connector for a cleaner installation: https://www.mcmaster.com/battery-connectors/north-american-style-battery-charging-cable-connectors-7/ I mounted one of these on the body lip under the rear. I use these on my hauler and they are used on about every tow truck out there. I have jumper cables that have the conventional clamps on one end and a battery connector on the other. Simply plug into the mating plug hard mounted on my truck (and my hot rod).
There are other choices too but these two are probably the most popular.

33Freestyle, My battery is in the trunk so easy to get to compared to yours, but even still I hooked up a battery tender pig tail to the battery posts so I can easily hook up a battery tender when not using it. You could go the same route and route the pig tail into the trunk.
This way you can plug it into a tender when not using the 33 so you wouldn't need to worry about jumping it at all.

Guys I'll look into both of these options. I just didn't want to over think this. I wish the previous builder had put an access panel on the back wall. It would have been nice. Thanks to both of you.

With the AGM batteries lasting longer than the old wet batteries, I find that the remote jumpers work better than digging out the battery. I like the remote jumpers so much, that I put them in both of my cars.

I used a battery connector and hard mounted it under the lip below the trunk. If my battery charger wasn't plugged in you'd never notice it in the photo. Makes for a very clean installation.
