1985 Astrovan Clutch, you do not need any special flywheel or pressure plate for this, that is what I used in my 52 coupe with a 55 truck engine. If you need me to, I can get the parts out of storage and show you a picture as I have since moved to an auto trans. Or you can just take the clutch hub you need to a clutch shop and have the correct diameter made for about $100 if you have $50 to throw away.
