Well, I've got some unknown springs that were pieced together from a waggy and something else, pretty sure they should ride okay. I know they have a decent arch to them, I'm actually going to go back to SUA on the rear, probably too on the front. I'm riding SOA right now front and rear, Chevy 4" springs on the front, stock CJ springs on the rear. These other springs I'm putting in have enough arch that it just might sit at the same height, probably about an inch or two lower in the rear. I'm not afraid of chopping the body up some. I'd actually prefer it to sit a little lower. It's fast enough and gets enough wheel speed that I'm not concerned with getting buried in the mud...it's a mud-skipper.
The front, on the other hand, I'm concerned about driveshaft clearance with the transmission pan, going to have to figure out what I'm going to do with steering, etc., when I go back to SUA...that, and it'll be a quite a trick figuring that one out on a Chevy front axle.
