The garage where I took it ended up putting one on from a local scrapyard anyway as one they had delivered was wrong type. Ended up being £190 all in.
That's with scrappy part, regas, new belt and labour.
Which wasn't too bad I suppose, and it saved me scrambling about at the side of the road.
Also said he would give me 3 month warranty, and if anything went wrong after that he would sort something.
It sounds much better than it did before, clutch used to bang as it engaged so should have guessed it was on the way out.
