I know how you feel. Just replaced the clutch & release bearing on the Sport as it was noisey. Could not remove the mainshaft as it's a SCCR box so one of the lads at work said remove the cluster instead of the whole box. Did it that way and rebuilt it all, the clutch is fine but now the gearbox is making a horrible noise Soooo piissed off. Just left it on the ramp at work and came home, another job to sort
