Alberta Guys!

there is a factory one that fits,,,problem is I don't know which one. I bought my duster and it had a drive shaft and a 4 speed in the trunk. sold the 4 speed but put a 383 and a 727 (it already had the 83/4 in it) in the car. Tryed the drive shaft just for ***** a giggles and it fit. So I don't know if the shaft was from the donar 300 or came with the 4 speed but it wasnt custom made
