I sent a post to Dave and the list concerning wheel cylinders, but didn't think to look at master cylinders -- will do so for a sampling this afternoon. I've rebuilt one Wagner master (64 Classic w/six) that I seem to remember as a straight through bore. Memory being what it is, I'll check the TSMs. Wagners were only used on Series 10 six cylinder cars from 58-69. I don't recall mine being Wagners, but I guess they were. The easy way to tell is that Wagners have trapezoidal anchor block on top with a flat end on the upper part of the shoe. Bendix has a round anchor block with a rounded shoe end to match. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
