looking for clutch master rebuild kit for early production 1968 1750 veloce with a Bonaldi master, cyl. parts places say N/A what am I supposed to do, junk the car? will any thing else work? I am used to reworking things. Also, can any make slave cyl. be used? mine does not have a m.f.g. name legible. If not, what are the differences? any suggestions sure would be a big help. THANKS !
