I can finally add my own wheels to this thread, which are: 17x8 fronts 4.5"backspacing 17x9 rears 5" backspacing Tires sizes are still up in the air, but sometime tomorrow afternoon I will attempt to fit a 275/40/17 in the back. For the front I'll probably run 245/45/17. So far, the rear wheels have a hair over 1.4" space between the lip and the leaf springs. Will update soon.
Mine fit 14's with disc. I like the staggered look of 14 front and 15 rear. Has 250 6 springs and sits perfect with the 302. Those 6 bangers are no light weight.
