OK, small ooops by me!!! Above, I mention that the Brake Master Cylinder seal is an old Alfa rear wheel cylinder seal....this is wrong. It is a master cylinder seal, or as Dave calls them "Fiat Seals" that evidently are used in a number of brake and clutch applications.... The part number and rest of the information is still valid.
Just trying to keep the record straight.... it's so tough with these old cars that were "Heinz 57'd" together from so many different parts houses!!
