I got a 69 Road Runner. It has a 1970 440/727 and 8 3/4 in the back. I have a driveshaft from a 69 (I think - could be a 68) 318 satellite 4 door. The slip yoke is for a 904, though. Can I just buy a slip yoke and change it out? Which one do I need? I also have a 68 Fury 4 door shaft with a 904 yoke. I may be able to pick up a driveshaft from a 70 318 challenger if that could work with a new slip yoke.

Thanks
