I'ld expect not, unless you found a throwout bearing to take account for this difference. The pressure plate and throwout bearing are specific both to each other and to the clutch mechanism. If the pressure plate is thinner I'ld expect a standard throwout bearing not to reach the full travel, unless you also modded the mechanism.

Are those rubbers firmly in (I've heard stories of rubbers being just too small and moving in their housings), and as far as there are metal insert in them did you grease them?
