Hi Andy, I now stock the rear crankshaft oil seals:

I also stock the thermostat seal kits, which replace all 3 seals related to the thermostat. There is a large seal around the thermostat itself, and 2x O rings (one for each end of the housing). The kit includes them all.

I've also PM'd you this information.
Thanks
