I had a pretty good exerience with 'Rotherham Spares', who contacted me after I put in a request for a rather rare switch, for a very old Honda, that seemed impossible to get hold of anywhere in Lanarkshire.
Worked out pretty good price-wise too, just thought I'd give it a mention if anybody is peeved off with trawling about car breakers, like I was. Spent enough on petrol trying to find the god-damn switch, so I was glad of an alternative.
Quite hard to find decent parts websites whilst googling I found.
Hope it helps someone,
Dave.
