Don't know yet. It all depends on where the nova sub ends up. I've seen some pics of swaps done, and they are on the low side. I hate anything lowered. I prefer close to factory ride height. The first things I buy is going to be rear leafs, shackles, bushings, shocks, and swap the 10 bolt in. I have to get the rear ride height set before I can tackle the front. Was going to go with a 12 bolt, but I already own the 10 out of the 74 nova for nothing. It will be fine for my app. But, when I happen across a 12 it'll be in there. I'm sticking with 15" wheels, don't like anything with a low profile look. May go 16" but no more. I haven't thought much in the way of tire size, but something around 235/75r15. I plan to run 3.55 gears cause I'm using a tb400. Low enough for the street yet tall enough for only having a 3 speed. MAY go 3.73, but that's a stretch. Keeping a middle of the road tire size like that will help with the overall gearing and launch factor. I can't go much bigger anyway, because I will have clearance issues with the front clip and the width of the nova sub. I've read that offset rims is a must to get the right width.
