The Stovebolt Site Forums The Parking Lot Big Bolts T170 2speed rear axle fluid questions?

Ok so if my driveshaft is 45" u-joint center to u-joint center, then I would need a 44" center to center driveshaft to give me the room I need. Would this size be likely to be on another c50/c60 of a different style??? Or would this be a rare thing to find?
