Yes you are missing that part. They are available from the vendors but my experience suggests you should have one re-metalled and machine to specs to get the correct actor clearance around the transmission shaft. Sen me a pm and I might be able to help.

John.
Something else is a miss in that photo. That drive plate should be back further, the end about inline with the back of those 2 bolt holes in the pan, uni joint should be about 3/4 of the way in it with the position you have that drive shaft sitting.

Some may not know that the early driven plates had a different spring locking retainer, with that they take a shorter fourth main, I have came across this a couple times, just in case you are ordering one some one that way they send you the correct style.

I don’t know if this is a consideration, but when I bought a roller bearing fourth bearing to replace the original babbited one, the directions advised for me to cut off about 3/8” of the ball in order for it to mate with the cavity of the new bearing. I thought about it and decided I didn’t like that idea so I took out my drive plate and sent it with the original babbited bearing to a machine shop and have the fourth bearing rebabbited and the drive plate shaft machined to fit it. I think I made the right choice. I sold the roller bearing fourth on eBay. Is it possible that your shaft ball was cut off for a roller bearing fourth? Jim Patrick
