Hi guys, I am having a custom driveshaft built for my car. I would like to get another used yoke for both the trans end and the diff. end, so that I can have them balanced as an assembly, without having to part out my stock shaft, in case I ever want to sell it, go back to it, put it on another car, whatever.

Does anyone know if the yokes are common to lots of Ford vehicles, and I could yank them in a junkyard from just about anything RWD, or are they specific to this MM/cop shaft?
