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.
