it is worth while getting the box rebuilt while its out getting the clutch done.
give Marco a shout over the box,don't think it will be done in time for the ring though.
if it does break you only lose 3rd gear though,still got the rest to get you home.
any info give me a shout.
i would give Stu a hand but i'm too busy in work and i'm doing 7 days still.
.
don't forget to skim the flywheel too
