Ken, I went right out and put the hub/rotor assembly on the stock 16 inch wheels (off the truck.) It looks very tight. I've beeen holding off putting everything back together until I got the new drag link and 1" tie rod, but am concerned about what I just saw. I hope to investigate some more tonight. Buffalo's spacer plates are 1/4", a little thicker than CPP's, Will report more later. :confused:
