Backing plate brake shafts

This is not a parts complaint but just something to be aware of.
I was helping a friend ream the backing plate bushings on his 34. Using an adjustable reamer and checking the hole with the new shaft we were just about there when after the next pass it went in rather easy. A little loose but not bad. He checked the other shaft and it was tight. He had grabbed a different shaft than what we had been using.
We then proceeded to fit each shaft to each backing plate. I did not do any analysis or comparison checks but just making people aware there are slight variations and you'll get the best results by hand fitting each shaft individually.
