In the Jun09 issue of Mustang Monthly on pg 42, there's a short blurb about
the 289/351W guys being able to retrofit the one-piece rear crankshaft main
seal from an '82-up 5.0L.  This is the same type of seal that is used on the
front of the crank with a neoprene seal lip held by a round steel carrier.
Although it does require minor block machining with the rear main cap in
place, this mod reportedly solves their rear seal leak problems.  The
question is, can this same trick be used on a 351C to solve our rear leak
problems?  Has anyone used this type of solution.
