What size tires are you running on the front?Big Steve,
I'm running 15x7 Torque Thrust II's all the way around on my 68'. The 255's are a nice size for the rear and I was told by the folks at Discount Tire where I live that I would not want to go any wider with that size wheel. The car has no air shocks but gives the illusion since the front was dropped by about 1.5 inches with the installation of the Hotchkiss cut down front coil springs. Check out the picture of my 68' in this thread: http://www.camaros.net/forums/showthread.php?t=108064
if you've got more pics, post 'em up here or in your threadSteve you should not have any problems. I had 235/60/R15's on the back before I switched to the 255's. You might want to reconsider the 235's on the rear and opt for 255's. I could email you more pictures of the rear of mine if you like.
