Gord, I have a 1954 Chevrolet 3604 with a 235 Engine. I replaced the clutch/ pressure plate with a PowerTorque K1874-06 Clutch Kit. ( clutch, pressure plate, pilot bearing, throw-out bearing, disc alignment tool ) The vehicle fitment says that it also fits a 1953 Chevrolet 3100 with the 235 . They are available from Orielly's here in the states and likely other suppliers. Its a 10" clutch disc ....the Chevrolet 1954 Specifications - Truck indicates that the standard clutch disc is 10" . A Heavy Duty option RPO 227 was available for 1954 and would have provided an 11" clutch disc. I'm curious why you have a smaller diameter disc, perhaps a previous owner did a clutch change and installed the smaller diameter disc. If you are resurfacing the flywheel and assuming its the original, you might consider going with the 10"... ( pricing online indicates $139.00 USD ) Hope this helps.
