I am going to buy a th400 on friday for 75 bucks the only thing is that the guy is into hotrods so it is a 2wd, but cant you just get a shorter shaft and a different tail housing? What all do I need to get to do it? Thanks for the help. Also what flywheel was more common on a 78 chevy 3/4t sm465? And also what all do I need to swap a sm465 for a th400? will my front driveshaft work? Thanks 38.5 inch ground hawgs on brandnew 15x10 white spoke eightlugs for sale. $200.
