Just for giggles... I took mine to Conrico LR in Chertsey for a quote.
GBP1540+VAT and they keep the old one as exchange, plus 2 hours to fit @ GBP90 per hour. I think they were offended when I laughed in the parts guys face. Just sourced one from ebay with the same problem, and have fixed mine in a position which is good for Wifey for now. Will be taking this apart and machining the cam assembly, and will post pics of the repair.
What boils my blood is that some old guy or lone female will have the same issue and will have to pay that amount to get it fixed as the know no better in most cases. These stealers are blatant crooks, who have a special place in hell along with their car salesmen counterparts.
