Distributor O ring/ gasket part #

I think after 10 years the statute of limitations had run out on hijacking a thread? :poke:
My issue is related??
The last oring I tried was Felpro 6464.
:rofl: Good call. My dumbass didn't even notice the date.

Is the bottom of the tang on the shaft bottoming out in the gear slot? Is the o-ring keeping it from going down? Maybe try it without to see if it drops.
