What axles did you use? The backspace will depend on the length of the axles of course, but my truck has the wider '72 style rearend, and I have 17x9.5 TT2s with a 5.5" backspace, and 275/50s. With these wheels, anything between a 4.5 and 5.5 backspace should work fine. The '67-mid '70 rearends are 1.5" narrower than mid '70 to '72 rearends, but again, it depends on the length of the axles you used. Here are the best shots that I have handy to give you an idea of how mine sit in the wheel opening.
