rear main seal needs replacing

[ca1a73]

Do i have to pull the motor or tranny to replace my rear main seal? It is an 87 302, I believe its one piece :'(

It might be easier to do that then pulling the trans, transfer case. It goes in from the rear of the motor after the clutch and flywheel are removed if its an 87 motor. One piece circular seal
