Will the break bands come out from the top, or will I have to pull off the housing to get the band out? Also the rear main seal that came with the gasket kit that I have is of cork and the old one in the seal housing is felt. I don't see a cork seal mating to a moving part lasting to long. But will it? Has anyone else tried it? Or should I try to go back with a felt seal, if I can get one.
