Using only a Willys as the starting point? You'll need to at least swap axles of course. I'd say spring over with uncut full
size truck axles. I assume this is what you mean.
Anyway, it'll work on rocks, but I think 44s are getting a bit carried away. It will be tough to fit the tires. You'll most likely
need to move the rear axle back and the front forward and cut all the rear fender well out. You'd probably be best off starting
with a CJ-5 frame ('72 ) maybe even a CJ-7 frame. I'd go with the CJ-7 frame if you want the rock buggy look, just put the
grill way out there with a couple pieces of tubing out there to hold it in place. The wheel base will help anyway.
