Thanks JohnRR, your answer pretty much clears things up for me. I was wondering what those codes meant, if anything, particularly the "H3" number. I havent taken delivery of the box yet but I do know its an A body.
I have no idea what that H3 is , but you have all the info you need at the moment , as long as no one has messed with it it's a 68 cast 4 speed trans for an A body .
