1969 Dart GTS340 on the way

Thanks for the information about the rear in my car . Smallest pinion diameter offered seems right since its an AC car .I talked to a friend with a shop and we will get it in there to see what needs doing . I will probably have him pull the engine out to get the engine and engine bay back in order.It should go pretty quickly if I take that route. Might as we tackle it head on . Once thats done and the bottom of the car is freshened up and re undercoated, shes going to be pretty darn sweet.
