I am trying to track down a clutch for my 91 Diablo. I have found a distributor that has a Veleo OEM clutch kit (clutch, pressure plate, and throw out bearing) for under $1000.00. The problem is the only info he has says that it fits all 91 and up Diablos. I have a 91 spare parts book and it looks like there might have been a change or an update to the clutch disc after VIN#12682. I have also have heard that the whole clutch assembly design changed around 95 and went from Valeo to Sachs, or Sachs to Valeo. Can older cars be updated my VIN# is 12352. If anyone can clearify any of this and or knows physical differences between designs I would appreciate it.
