Roy,

I recently had the same dilema with my 65. My clutch master cylinder would leak
fluid all over my left foot everytime I pushed the clutch in. Since the Master
Cylinder looked to be in pretty good shape, I decided to try to rebuild it. I
got the rebuild kit from Napa, but the diameter of the piston and the rubber
gromment that came with it was smaller than that of my MC. My MC looks identical
to the one in the shop manual, but apparently it isn't stock. I took the MC into
Napa, and the parts guy tried to cross reference all the numbers on it without
any luck. I was lucky that day though as the guy was very patient, and searched
all his rebuild kits for one that had the rubber gromment in the same diamater.
I bought the kit that had the right sized gromment, honed out my cylinder and
attached the gromment to the existing piston, and all works fine now. My foot
stays dry, and I don't have to fill the resevoir every weekend. 

Be careful buying a used MC sight unseen. I did this, and what I received in
the mail was definately NOT the right part. I only paid $10 for it, so I didn't
bitch to the guy about it...

Good Luck,
