For those interested, I received and installed the High Performance oil seal
for the Ross PSRU.  The fit into the bellhousing seal housing and around the
drive shaft appears to be good.  The sealing area around the drive shaft  is
much more robust than the National type seal previously used.  The seal
material is thicker, stiffer and appears to a high performance synthetic
material that forms the lip of the seal around the drive shaft. There is no
spring around the lip as there is on the national seal.   It also has what
appears to be a band of UHM (white) material where the drive shaft exits the
rear of the seal.  Purpose of this band appears to be to provide more
substantial low friction support to the drive shaft (speculation on my
part).

 Sorry, no photo of seal, but it appears as in the attachment.  The drawing
shows the darker lip sealing material as well as the lighter shaft sealing
material.

Unable to test run the engine at this time to see what the operational
results are as I am rewiring for Tracy's EFI/Ignition unit.  Should be able
to run it in about two week or so and will let the list know the results.
