man changing a clutch on a 8v gti mk2 aint all that easy. i changed the gearbox on mine on my drive and it took about 3 hours to do split over 2 days. in a workshop yeah fine probably could do it faster but deffo not an hour and a half. my mate who helped me is also vw mechanic for local dealer and he said he couldnt do it much faster even if he had been at work as they get 5 hours or something for gearbox change.
on my nova with a 6speed g/box and turbo motor, some muppet (as in me) had forgotton to apply correct tourque to flywheel bolts and they became loose while running it in. we had the box off and back on tightening the bolts up within about 2 hours and that was 5 of us absolutely flying at the job.
clubgti is ok, but as someone says they dont seam to reply unless they know you and it seems technical problems dont get answered either. on here miles more of a laff and useful aswell. almost as good as migweb the vauxhall site, just not as many members on here
