Does anyone know if a 1972 Cadillac transmission will fit a 1972 Pontiac Catalina Safari Wagon? I have been told that it will. The '72 Cad Trans has a 13 bolt pattern on the fluid pan with Hydromatic stamped on it. This matches my Pontiac THM400 Transmisson. BUT, the Output Shaft is 13" to my 9". I realize that cutting down the drive is necessary if this is a match.
