Hi Don,

  I just lQQked over the Rear Main Seal article. I see that someting I wrote 
a long time ago about seals and bearing play is in there. Kewl.

  The seal you are describing is not "do-able". The reason being is because 
the flange where the torque converters flexplate bolts to,is of a much 
larger diameter than the journal(bearing surface) that the seal rides 
against.

  If the seal was made one-piece like a rubber-band...then stretched over 
the end of the crankshaft and postioned on the journal...then the retaining 
cap tightened down..?  Possibly someone can invent this. But I doubt it 
would be as fail-safe as the original design installed correctly.

  Why do you ask? Is your seal leaking?

Steve from Albany,N.Y.
'75 Imp 4dr <--orig seal,no leaks.
'79 440 powered 35 ft RV <--if it does leak,there is lots of room to work.
