You are going to need to cut off the rear coil spring (towers) mounts flush with the upper frame, you will then need a SN95 rear (slightly wider than a 79-93 fox rear end), at that point, you are best to spend a little extra money and get the FFR 3 link retrofit kit. You can then add the 17x10.5 rims (94-2004 offsets) in the rear in order to fit the 315/35/17 tires, yet you still might have some clearance issues, again, depending on which rear axle/housing setup you have.

If I'm going to swap out the rear anyway, are there any affordable IRS options? Or is that an entirely different price range, with shocks, brakes, etc.
