There was a good article in one of the magazines awhile back. It was called "38s, an airsaw, and you" or something. I believe it was in JP. I am actually trying to find my issue of it for a buddy of mine. If anyone knows what month that article was, please post it on here. They show where and where not to cut on a Cherokee. But for just 35s on 8" lift, you shouldn't have to cut too much. I'm running 8" lift and 36x12.50 TSLs on 10" rims with 3.5" backspacing and I only had to beat in the forward and back edges of my rear fenderwells. Mine'll flex pretty darn good too. The front was a different story... a lot more trimming up there and even taking a hammer to the floor boards for a little more clearance. With 8" and 35s though, you shouldn't have to cut too much. Good luck and post some pics. I'm going to try to attach a couple pics of mine to show you how much I cut. I've never attached pics on here before though so I'm not sure if it'll work. The pics aren't closeups but they'll give you an idea at least.
