I have a 67 and I'm rebuilding the stock, matching numbers engine. Does anyone know the correct bellhousing, starter and clutch part numbers/size? I believe them to be 3899621 bell housing, 3791021 flywheel, 1108338 starter and a 11" clutch. Just want to be sure, cause I have a 3858403 bell housing and it doesn't fit the 8338 starter!
