I've seen that a 1971-72 Road Runner has a 115" wheelbase and that the earlier Road Runners/Satellites have a 116" wheelbase. My question is, in theory, would a driveshaft out of a '71-'72 Road Runner work in an earlier Road Runner with the shorter driveshaft?

I'm assuming here that the later driveshaft will be an inch shorter than the earlier ones, but will that make a huge difference for just a driver?

Thanks
