I have a saginaw that was pulled from a camaro. The main case number is 338935. The tail shaft housing number is 352254. The side cover is 6261886 There is a J101 Which I believe is a date code but not sure And a 172109821 that I believe is a vin number but does not match the camaro vin. Can some one help me in figuring out what I have and what its out of originally. I do know for sure its a 4 speed saginaw by the photos on a couple different web sites. I just can`t seem to be able to find anything out on the numbers so as to figure out what gm car or truck it came from originally. Would some of you saginaw gurus straighten me out please?
