Joe,
You might just pull the sump to see if the rear metal seal holder has been
modified (small non-critical ?ears? taken off at the left and right edges) to
allow the rear main cap to be removed while the engine is in the car. I
haven?t tried it but I think the seal can be replaced without pulling the
engine if this modification has been done.
