You have to use A3 clutches. The a3 clutch shoes have smaller pins than the A35/A55. The hubs and bells will not interchange either. I'd disassemble the clutch an inspect all the pieces. If everything is in good shape except for the friction material you can re-bond the shoes yourself. If the slots in the hubs are worn or the pot metal shoes are fracturing you'll be better off finding good used parts.
