Fishmarket...
Are you looking for your 71 B-body? Curious because I am shopping for tires for my 71 Charger. Since I want matching brand/tread on front and back I was leaning towards....

Nitto 450's
255/50/17 front on 17x8 (27.05 overall height) 4 1/2" backspace
275/50/17 rear on 17x9 (27.83 overall height) 5" backspace

puts it somewhat close to what a lot of people are running (height) in 15" tires.
235/60/15 front 26.10
275/60/15 rear 27.99

I figured the extra 1" height in the front would help with the "level" look. However I am NO expert! The main thing that worries me is putting such a wide tread on the front. Wonder how that is going to drive???
