front driveshaft length...

[-Nathan-]

Hey guys, I have searched to no avail. I need a front driveshaft, as mine is pooched. I was going to rebuild the double cardon joint, but the stub on the shaft is wore, so it wont stay centered in the ball.

A-1 cardone lists two lengths of prop shafts, 39 3/8" and 38 1/4", but I CANNOT for the life of me figure what application is for which?

My truck is a 2001 Ford F-250, 7.3 powerstroke, 6 speed manual, 4x4, extended cab

Any info would be helpful. Do I need the 38 1/4 or 39 3/8" shaft?

Thanks guys.
