I recently acquired a driveshaft from a mopar guy, but he could not remember what it came off of. I want to see if it will work on my 71 Challenger that will be a 440 car with a 4 speed. right now it is a 318 with a 3 speed and i think it is shorter. The new one I got is 52 or 53 inches center to center. What do you think?
