Sorry for not getting back to you ive been away for a few days. To answer a few of your questions.
1. Its a struggle to get it into gear, and when you get it into reverse there a hell of knocking noise as if theres far too much backlash. Ive already changed the clutch, slave cylinder and master cylinder.
2. On the gearbox thats in, reverse gear is beside 4th gear and i will have to check the spare one never thought to check that, what a numpty.
Decided to have next week off and get it sorted once and for all, spanners & hammers will be flying so watch out.Thanks for your help.
