HI JIM , Can you clarify, you rebuilt your OE MC which was 15/16" bore with Raybestos Kit MK697?
The reason I ask is because I have 2 Bendix 1" Bore MC's that I have been trying to find the right rebuild kits for , with no success. The difference between mine and yours is bore size and the pistons in mine are retained by 2 pear shaped retainers that get removed when the MC is installed. Yours uses a "C" clip . This difference i can only guess effects the stroke if that makes much difference , I don't know
