Uncut EBs are hard to come by, if you have one that is in good to excellent body shape, I would strongly hesitate to cut it. If the body already has some serious cancer and has been cut up to take that out, then I would lean towards cutting her. My 72 had a lot of cancer when I redid it so I cut the fenders. With a 3.5" lift, you are only going to get a 31-32" tire under it without a body lift. To get any articulation, you will need to get different backspaced rims and you will need to flatten the inside drip rail on the fender. The setup I ran on mine before resto was 3.5" susp. lift, 31s, no body lift, J**p rims, and I was able to completely stuff 31s in the fender well without rubbing. But I stress that you flatten or cut the drip rail on the fender so you dont slice your tires and tear the fender up. Also get different backspaced rims to makeup for lost space.
