I'm going to look at a car this afternoon that is my buddys, his father died in an accident recently and informed me about this car that his father has owned since new and from what he says is in great original condition. At this time the info is a 68 coronet w/4 speed and a big engine. I was wondering without knowing if its an R/T or 500 was it possible to have a 4 speed behind any type of motor for that year?
