Rear main Seal  This is the latest generation
rear main seal.  Don't need the soaking in oil like
in the past.
NOTE,  While you are replacing the rear main

I do lots of Seibenrock special orders for seats, cylinder kits etc.  Prices are generally the same as
what Seibenrock would charge.  They've gotten better at shipping though still relatively  expensive and
there usually is a currency exchange charge.  Neat stuff, glad to do it, just let me know what you want
and we can see what the deal is.  Jeff
