Nice results on the wheels/centers! As a side note, I picked up a set of billet aluminum hub-centric spacers for my '70 C10 2WD. I have 17X8's and, as mentioned earlier, had an issue with the rear wheels sitting further in the fender lip than the fronts. I just used 1/2" plain spacers (no studs) to tighten up the fitment. I provided all the measurements required to ensure a perfect fit from axle flange to wheel. Very happy with the quality. Here's a link for anyone considering that option.
