    Yes BA & BS

    Early models got the BA, late models BS, depending on the build date, a mid year change. I used 4 sources to verify it.:Smarty:

    Congratulations on your purchase Derek!

    This is a very good discussion on the 1971 transmissions - thanks everyone. Here's what I have for 1971 TH400 documentation (thanks to Dan Healey)
