They kept the ball and trunnion shafts with NP833 early style output shaft and 4 bolt tranny style front U joints Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

So upgrades are available. Swapping from the 62-64 tailhousing and output shaft to 65 parts will allow you to run a standard style drive shaft. Though there is a raised area just ahead of the output splines on a 65 shaft. The later yoke needs to be shortened about 5/16". Doug

Doug when you say the later yoke needs shortened, is that the factory style with the [approximately 1" of missing splines at the front], or the shorter aftermarket style with the yoke having all splines, or both ?

A 10" cut off wheel in a miter saw is slow but cuts them with no issue. you can see the rib im talking about. Doug. That rib is to keep the o-ring (a ribbed affair about an inch long) in the slip joint so trans fluid won’t run back out the splines. All the slip joints I have are smooth in the front half, no splines. If that trunion will hold up to a 600 inch Hemi I’ll use that trans in the 64. Last edited by cudaman1969; 04/09/24 07:59 PM.
