Blykins Every bell housing needs to be checked. You may get lucky and not need any adjustment. Unless you have a strange motor to trans combo, I don't know why you would not go with a Lakewood housing. Multipieces being "BOLTED TOGEATHER"? No thank you. I am sure that Mcleod has done the tests to ensure there bellhousing is SFI rated. I will stick to a 1 piece bellhousing. Is there pins to keep the pieces from moving around? The rear plates are inter changable. I would weld those pieces togeather after it was centered. 1 bellhousing to one engine block. Togeather for life.
