    The oil sending unit is a small cylinder that should be located up on the intake manifold near the back behind the carb.

    As far as your rear main seal, '85 was the last year for the 2 piece seal. Once you get the oil pan off, all your need to do is to knock the upper piece out with a driftpin until you can grab one side of it.
