Unfortunatly this may not be the info you need but at least some encouragement. I rebuilt a 15CWT and was not able to get any match up for new wheel cylinders from the parts shop I usualy dealt with there seemed to be no intrest in the problem- bugger off. I showed a cylinder to a neighbour and he sent me off to another shop. The parts man said yes he thought he had one in stock which he did and ordered the other three! Unfortunatly I didn't keep the part number but it was a common stock item. There is a new stock wheel cyliner out there you just may need to really look for it.
