I've had that driveshaft out in that truck's lifetime for u-joints and a center support when it belonged to my FiL. But that's decades ago, and I don't remember how much more of the splined shaft is available. Anyone have one in a position to tell how long that splined portion is? I'm drawing a blank. I know for a fact that that is the driveshaft that was in it in '81 when I got married, so I'm expecting it to be original. It'll be interesting to get to the solution.
