Hi everyone, I need help finding replacement rear wheel cylinder. The bleeder screw broke off inside. I was able to get the cylinder out to work on it. Bleeder hole/threads pretty boogered up by the time I got it out. I was able to drill and re-tap -but worried about the strength of the threads. Delco is cast into the housing, I can't seem to put together any sort of part number string. I've searched all the stores by make and model and only rebuild kits can be found. It is a 7/8" bore -as cast on the housing. Any thoughts on alternate part number or interchanging cylinders?
