The cup style retainer in the link works well. On my 3rd gen F body I removed the pedal quadrant and mocked it all up on the bench. I welded in a flat piece of steel with a hole drilled in it which guides the rod and prevents it from dropping out of the Mopar MC. Also a stop to prevent the pedal from being yanked back. At one time I used a cast iron MC from a GM pickup with manual brakes and it had a pushrod that locked into the master cylinder piston.
