I haven't picked a specific filler yet. Summit has some Dorman fillers that are obviously used by the aftermarket, even though they are vehicle specific. It is surprising how difficult it is to find the dimensions for oem parts. I went to my local Auto part stores to see what they had, they looked at me like I was crazy. They don't stock anything but 1000 of the wrong size belts, over priced batteries, and air fresheners. It's only a matter of time before everyone just orders from Rock Auto. The parts stores are happy to order things in, but if I have to wait and it will be overpriced and probably wrong, I'll just cut out the middle man and make the mistakes myself.

I'm really interested in finding one that is 45* bend right after the filler neck and then has an extension that is 2". I plan to use a locking modern gas cap, like a Jeep, and no filler door. Hopefully that makes sense. I will bolt it through the filler panel like what TA_c10 made (which I looked through your build thread and couldn't find, maybe the pictures got eaten? Stupid question, but do you still have a paper template to scan?
I also got my shocks in the mail. I spent part of this evening offering them up to design a bracket. Things are looking good. I'll need to get the coils on though to make sure they clear the tires, and then I'll start prototyping and welding. Trying not to overthink it...
