Yep, they have one. 1986 and older has a two piece rear main seal. 1987 and up has a one piece rear main seal.
1986 and older are 2 piece.
The engine rear main seal can only be replaced with the engine or transmission out of the vehicle.
I'm for sure that it is a 2 piece seal. You can call the parts house and tell them the year and engine size and they can tell you. Are you can look at the back of the engine and tell for yourself.

1986
You can pull the transmission or engine, witch ever you think would be the easyest for you. But you have to remove one of them to replace the rear main. It is a 1 piece seal and it drives over the back of the crankshaft.
Pull the engine.
You must remove the transmission are engine to replace the rear main seal.
You will need to remove the transmission.
Engines used during that time used raised-rail heads and a one piece rear main seal.
