Seen as you're in no rush, I'd leave them for sale a little longer.
As for the dial insert I got mine from that bloke in Poland. The
problem is he shows in the pictures in the listing that what he sells comes with 1, 2, 3 x1000 rpm, however what he sends comes as 10, 20, 30 x100 rpm. I can live with that. However there are other problems, such as he sends them out with all digits on the cluster the same size, which is wrong, because if you look at our clusters the speedo digits are slightly smaller than the rev counter digits.
To tell you the truth I wouldn't bother doing the mod, I want my money back off him as when fitted it looks nothing like as good as it does in his listing.
