I am running a G-60-15 McCreary..It's a fairly small tire compared to what you are running and I have no clearance issues anywhere..The only thing I had to do was trim the rubber snubber thingy on the side of the rear frame rail....The 67s have this in a different spot and it won't be an issue...frdnut, what tire do you run? Did you mod the front inner whell house? I use a 5.5bs on my sn95 8.8 which is about 3/4" wider per side. When I buy axles I will make it stock 67-68 length. My 275/50 M/T DR's touch occassionally on the outer wheel house on a big dip when loaded down going to the strip. I will have to mod the front inner wheel house when I shorten the rearend to stock length.
