I got 4 rear tj flares. I've cut and extended my rear wheel wells about 2.5" mocked up around a 37" (I'm on 33.5" tires now). I have no doubt the 35" tires will tuck in there nicely. The TJ flares had planty of room to fit around the rear even with the extension, coul probably go another inch or two.
unfortunately I cut up the front of the wheel well too and extended it. If I had thought about it, I would have left it a little longer, and maybe welded some nuts to the back side of the sheet metal while I had it apart...that might have let me mount the flare to the quarter panel rather than the rear door. Oh well too late.
