18" wheels

I was thinking of these in 18x8.5 with +35 offset (6.1")on my 69 Barracuda FB with either 255/40R18, or 265/40R18 if I can get away with a 26.3 diameter. The wheels also come in a +24 OS as well, with the possibility of getting a custom OS. I will wait till I get my disc setup installed before I order. My main concern will be the front, b/c I will be adjusting a b body rear to the proper size. What do you guys think?
