1965 833 4sp. tailshaft seal R&R

Hey guys ! I have a rear tailshaft seal leaking oil out of a 1965 dart 833 trans with the trunion driveshaft . can anyone tell me the procedure how to remove and install another new seal.. I seen two different style seals for this1965 833, one with a rubber boot on on a seal and another that looks like an axle seal.. Which style am I looking for since I did not remove that bad seal yet?
part numbers ?
Thanks for all your help fabo's!
