Thanks a lot...

Ok. I found the bushing on the Brewer's performance website
Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists

Is it tricky to remove and install?

Remove the tail shaft use a 1 1/16 socket use a heat gun on the outside of the tail shaft and hammer the bushing out
