[Spridgets] Need Rear Main Bearing Seal

[Paul Asgeirsson]

Hi Bruce,

That's a part that doesn't interchange well.  The one that was on the engine
ideally should be there.  BUT! If you're going to rob one from another
block, it should be line bored so it fits properly.

A 2"main one from a 1098 might fit initially OK, but save yourself some
grief and get it line bored.  It's part of the rear main scroll seal
arrangement and requires close tolerances to work well.

Best, Paul A
