69 chevelle big wheel question

[zx10intn]

ok, i know many of you do and many of you dont agree with putting large wheels on these classics, but i like the look and have decided to go for it. i have read for hours, and just need a little help with a couple of questions to make sure what im hoping to order will fit. im planning on running these wheels, http://www.marshalltirecenter.com/pr...uctId=10888100 , in a 22. the front wheels will be 22x9 with a 5.747 backspace with a 245/30/22 tire. the rears will be a 22x10.5 with a 6.497 backspace and 295/25/22 tire. there are a few backspacing options available with each, but what has me confused as to which one to go with is I have the 12 bolt rear end on mine, which i understand is shorter im not sure which option is best for me. anyone with advice on this decision is greatly appreciated.

the 1964-1967 12 bolt is shorter. make sure what you have. your car should look killer. better make sure those 22's will clear in all directions, unless you are going to put a lift kit on it or serious lowering mods.
