I own an 84 TA. It has the original tranny in it. If I were to ever want to upgrade to a newer 700R4, from say a '92 TA (This is the year of engine I'm getting as well... the 350) would it be a direct bold on, or would things like mounts and yolks change? I know the connection between the 350 and the current tanny needs the 350's parts, but that is obvious. Thanks for any replies.
