They call this style the ball and trunnion style for the B & T driveshaft that bolts to the flange on the output shaft of the trans. It is one stout transmission used behind everything from slants to a 426 Wedge and maybe even the Hemi in 64/65. The reason is the B & T 833 has an extra bearing in the tailshaft where other 833s don’t. The easiest way to use this transmission in a letter year car is to do the slip joint conversion to the driveshaft as described elsewhere here in FABO and on the early Barracuda forum. I will be using this conversion driveshaft in my 65 Dart wagon rather than the B & T driveshaft
