So if I call up a pressure plate manufacturer like Hays or Centerforce and tell them I have a 1977 Dodge van with a three speed and a 225 slant six the pressure plate would fit my car? Is that possible?
Yes, just the pressure plate and disc from the 6cyl. truck/van along with those bolts. The clutch is a little over 10" but still fits the early flywheel and bell housing. The release bearing is the same also.
