how to ID driveshaft?

is there a listing of driveshafts by what they fit by lengths?
have a 727 small ujoint driveshaft that is 61 inches center to center. trying to determine what it is out of.

I believe there should be a part # lightly stamped on the shaft body and you can ID by that?

yea, good luck with that. I have a small pile (probable 10-15 left) of Mopar driveshafts that have been out of vehicles for years, but have been stored inside. The problem is, they were under the cars they were in for years before I ever saw them. You wouldn't be able to see a stamped number on any of them. too much dirt and rust, and cleaning them off would remove the numbers. I've never see a listing based on the length, something like that would have been really helpful through the years. Gene

Post length from center of U joint to center of U joint as well as outside dia. Galen's white books contain this info. Someone here will provide a reply with the application. Joe

There is no 61" lenght in white book. Its so long and no performance cars had one that long. My guess a large C Body or Truck

ok thanks

Yep, Spicer U-joints says C-body/truck.
