Hey all, Here are pics of the box and sector shaft we are trying to find the application for. We seem to think it's a gemmer box, but maybe not. The casting number we got off the box is #3386551 and the portion that mounts to the frame has a casting # of 2599. The diameter of the sector shaft where the seal rides is 1.25". We are in need of a sector shaft and seal if available, but would like to find the original application before I pass the hot rod down to the kids. Any pointers to where we might find help would also be appreciated, thanks for your help. Larry
