This 3-piece Injection Clutch uses the larger 190mm wide valeo clutch plate and a Valeo pressure plate which could be used on earlier non injection Verto type engines only if the flywhel is 100% perfect without wear. Check nothing fouls when bolting up in case of mismatches. Non injection cars do not need the alignment correct to work but Injection cars do require the correct assembly. Valeo and AP pressures have 35 degrees difference in alignment so incorrect fitment will stop the engine starting. Use your original center boss to ensure correct pick-up.
