Thought I would let ya'll know some stuff I have learned while rebuilding the brakes on my recently purchased/trying to bring back to life '59 c60 viking grain truck that was last tagged 21 years ago. In working on the brakes I found a master cylinder rebuild kit for 1"1/4 bore at NAPA part number UP33 and a reman master cylinder of the same size bore is part number P21698. It fit perfectly and was about $20 bucks more than the kit. And wonder of wonders, they had one in stock and do request a core exchange.
