NEED TO KNOW THE YEAR. Some years had the 2-piece seal and some had the 1-piece seal.
All engines after 1986 give are take a month have the 1-piece seal and you must remove the engine are the transmission to replace the seal. OIL
Pan does not need to come off.
If it is older then a 86 then you will have to remove the oil pan and the oil pump and rear main cap on the crankshaft to replace the seal. Either way BIG JOB.

If it is a late month of 1987( Build date) then it has a 1 piece solid round rear main seal in it and you will need to remove the transmission and fly-wheel and then pop the seal out and drive the new 1 in place. If it was built before late 1987 then you will have to remove the oil pan and rear main cap to service the rear seal. It will have a 2 piece seal in it.
