Chevrolet, GMC - CPP 12 bolt disc conversion issues

The 1967 - 1972 Chevrolet & GMC Pickups Message Board - The 1947 - Present Chevrolet & GMC Truck Message Board Network - 67-72chevytrucks.com
Hi everyone, I am using the disc brake conversion for the 12 bolt rear on my truck. I am having trouble getting the outer pad to clear the rotors. Is there something simple I am missing? I called CPP and they said this rarely happens but they have seen it and are sending me multiple smaller shims to replace the single shim that was meant for the swap. The axles are bottomed out on the "center pin" but is it possible I got something out of sync causing the axles to sit out? I dont see how that could be but then again I dont have much experience with rears. I need under a 1/8th of a inch more clearance for them to slide over. I figured it would be worth a post while I wait for the smaller shims
