Does the oil pan have to be removed to change the rear main seal on a ford 3.0L V6 in a 2000 ford ranger?

I have the engine removed from the truck and was swaping in a salvaged engine that all checks out good except for a slight leaking rear main seal. So, after inspecting the rear main seal, it appears as though a could just slide it out and a new one in. Does the oil pan need to be removed? Or can I just carefully remove the old seal and clean the surfaces good and install a new one?
