Okay, so doing the sm465 swap for what seems to be a saginaw 3 speed on my 72 blazer. I have the sm465, transfer case adapter and a new 205 to go with it. My question is, before i teake everything apart, will the bellhousing from my heavy duty 3 speed work with the sm465. Or will i need a different one, along with probably all new clutch components. Thanks. Dont want to tear into my truck again, and then not beable to swap everything and have my truck sitting again.
