Here's a pic of an actual FG beetle. Looks like the ass end is just kinda big regardless.
What I did notice tho is that the inside of the tires on the FG are even with the edge of the body. They are tucked about an 1" in on the Sav. Hopefully getting the wider track and the body better mounted and painted will solve the dimension issues.
Been really busy, but what I aiming for now is getting another set of tvps cut with a few tweaks now I know the WB I want. I will focus on getting the TVPs done first. I did measure out what I need to cut out on the FLM bulkheads, and its going to be a bit of work, so that bit will come later. The truck will drive fine in the config it is now w/ the Sav arms, so no need to rush it.
