Well Dave,
I've had them side by side on a couple of occasions. Near as I can tell
they're identical except for the main bores. The fluid feed holes appear
to be in the same place. I have a friend in this situation right now who
is about to go $$$$ for a new master cylinder. I'm sure he would be
happy to be the guinea pig to try the rebore route. Now about those
pistons ..................???
