I tried a set of Federal Mogul 6-3755APA years ago and the bearings were too wide. The FM 6-3755AP was the number for the stock bearings, and they fit ok. The wide bearings fit a stock crank just fine, but locked up on the forged crank. Those numbers are no longer available, but I don't know what replaced them. I would like to know the width on the Park Avenue bearings. Of course, the wide bearings can be chamfered on a lathe with the right holding fixture made from an old rod.
