Darius, I'm in the process of recovering my Westy interior with new covers. I'll have the old covers left which are a bit rough but could be cut up to make the smaller bits you need. I also have the over engine bit which is complete but stained. Any use to you?
I was considering a change of colour, i have found a beige to match the front seat. To be honest it is on the seat base that has a hole in and a corner of the stool, maybe what you have left may work.
When do you want them? If I bring them along to Volksworld, is that too much of a wait? You could pick them up from my work (Cowfold) if you want them sooner.
