The torque convertors interchange between a 200C and the 200-4R too. Double check the trans model. I pull 109 blocks all of the time and they are usually 250C/350C trannys.Hows the underbody look? If the suspension is clean those parts also might be worth keeping. Its always handy to have a spare set of control arms if you do the poly bushing upgrade. Door hinges are also worth keeping.
