I have 3 clutch brackets, the one without the ball is ‘55-‘56 Ford with a Y-Block, the 2 with the balls have the same bolt pattern spacing and I’m thinking they may be for a Mercury of the same year since they used a ball on both sides of the Z-bar. I can’t find a picture or anything online to compare these to.
Hopefully someone can verify. If so, there is a clamshell bearing that goes around the ball on the Mercury. Is that available anywhere?
Here is the parts diagram from the ‘55 Mercury clutch ***embly. The rubber washer (7539) ID is 37/64” and OD 15/16”. If the two ball stud brackets have a base measurement near 37/64”, you should be able to use one.
Thanks for posting that scan, I tried finding it online but had no luck. The bracket that I have with the ball looks nothing like the one in the picture, the hunt continues.
