your '59 is) then consider yourself lucky. That is a much
better seal than the rope seals were or are now. They are a
contant problem and leak 98% of the time even when properly
installed.
.020" off the rear main bearing surface is nothing to be
concerned about, that only amounts to .010" at the sealing
edge. A neoprene seal is much more tolerent than that.
I would suspect that the seal is not being installed properly or
is being damaged when it's installed.
