The disc is the same thickness anyway You put it in , but it will only go in one way , check Your throw out bearing if it is the short and You will need the long type , it all depends on the total hgt. of the old clutch and the new one.Take old setup and set it on workbench measure hgt. with throwout bearing do the same to new one than You will know what size bearing to install to keep hgt. the same or close. Some new clutchs are shorter in hgt. I hope this helps ,Pete
