Danny, where abouts are you located? If you are anywhere near Bradford (west Yorks) my best buds brother in law is THE best gearbox mechanic around. He'll give you his opinion on the problem for free, and will sort you out a dam site cheaper than anyone else could. Hes been in the game 20 years and theres very little he doesnt know. My clutch needed doing and he offered to help me do it and im not really an expert, but we had the gearbox out, a new clutch in and refitted in 2.5 hours. Let me know if you want his help.
