Default Re: Rubber Rear Main Seal
What might be interesting to know is that a rubber rear main seal has been produced in the past. I just scored one on Ebay, they are new old stock.

The number is Detroit Gasket 17091 (there are more numbers, BS40048 is used also, but in conjunction with the rope seal)

This is a lip seal, consisting of two halves with a steel backing for rigidity. I'll upload some pictures later today. I'd be willing to help out with any info you may need, as a good rear main seal saves a lot of grief and oil soaked driveways.
