The thing is; they were never intended to last 40 + years. The fact so mant did says the Chrysler engineers did a good job.
I have mechanical Aptitude. I can screw up anything.

I'll jump back in here and ask a couple stupid questions:
1) Do you have to pull transmission from the car to pull the tail-shaft? 2) If you did cut off that ear that holds the pin in, would the pin slide out so you could replace the O-ring?
If the answer to both the above is yes, then I could see the benefit to trimming the ear, and then adding a bracket to the bolt to hold the pin in.
Wouldn't this be an easy fix for us shade-tree mechanics would don't want to pull the whole tranny?
1) No, you would not have to pull the transmission to remove tailshaft. You can also cut dog leg off w/o removing tailshaft. Metal is very easy to cut with hacksaw blade.
2) Yes, once the dog leg is removed, the pin will slide out far enough to remove old o ring and install new o ring. I would not slide pin out any farther than pan rail lip of tranny. I will post pics of what I substituted to hold pin in.

You were sooooo right. It was coming from somewhere other than the pan gasket. It was seeping around the pivot pin. .....
Ooh Ooh, did I call it or what! Glad you found it. Leaking cars suck especially on new concrete driveways!

Does seem like you could add a piece to the bolt above the dog leg once you cut it off.
Post what you end up with.
Here is the pic of dog leg cut off from tailshaft. When I pushed out pin to replace o ring, I pushed it out past tranny pan rail lip. It would not push back......like there was a stop preventing it. So I removed pressure on pivot pin by backing off band adjustment nut. Then it pushed right back into place.

Then I needed a rod of some sort..........very stiff so as not to give to hold back the pin. I found in my box of parts a brace.........maybe once used to brace a dash.

I bolted the brace to the auto tranny shifter brace (not sure if this is proper name) and the other end of brace is NOT pressed against pin. There is approx. 1/8 inch gap between end of brace and pin.

With the 1/8th inch gap, pin can slide back and forth like original set up. When o ring starts leaking again, you don't have to remove tailshaft. Just remove pan and brace, you're done in a fraction of the time.
