Wanted - rear seat pad for 851 SP3
 

I posted this on the Market Place page, but in case here it is again...

This is a bit of a long shot, but does anyone have a spare rear seat pad ("bum stop") for the single seat unit on an 851 SP3? It doesn't have to be in good condition as I want to recover it anyway with much less padding - in fact, just the plastic backing would do.

TIA
