would someone please confirm that this is correct when reconnecting the drive shaft to the transmission:
the trans, then the universal ball cap, then the ball , then the ball is screwed to the universal ball cap and trans?
Since the ball has its own plate to be screwed to the trans, I didn't know if the universal ball cap is needed.
Thank you, Bob

Yes the ball's is a must. You use a gasket on both sides. The cap is there to support the output shaft of the transmission.
Gasket between the ball cap and trans, not between the ball cap and retaining ring.
The fourth main,or ball cap as you are referring to it,only uses one gasket.The gasket goes between engine pan and the flange on ball cap. If you put one on the outside and bolt up the differential drive shaft flange ,you are allowing a large gap. This gap will cause rear end to move forward and backward,and is not good.
Robert, The ball cap or "fourth main" as it is usually referred to, is a must. It supports the weight of the transmission, and keeps you from breaking the crankshaft. It also should fit the transmission shaft very good. About 4 thousands would be good. 2 to 3 thousands would be better. If it is a very loose fit, your crankshaft is taking a beating. Also, make sure the hole is up. As mentioned above, one gasket only, between the trans and the ball cap(fourth main). Have fun, be safe, work safe
Be sure that the ball cap (4th main) has the oil hole up as you show it and the grease fitting in the collar ( captive on the drive shaft tube) is also up. The drive shaft tube grease fitting for the drive shaft housing front bushing also needs to be up when the rear end is assembled.
One other little detail. Have the grease cup already screwed into the driveshaft cup before you do final assembly. Then make sure it does not stick out into the ball area or into the grease hole. The threads may have been over torqued in the last 80 to 100 years allowing the grease cup to go in to far. I have had to grind the end off the grease cup threads to make sure it will not hang up on the grease hole or score the drive shaft ball.
Don't forget that the bottom 2 bolts need to be safety wired.
Oh yea, I forgot about the safety wire! Thanks to all of you!
