Is there anyway to visually tell if a master cylinder is a '77 ? Casting number?
The reason why I ask, is that my m/c started to seep a little brake fluid. Went to get a rebuild kit for it, only to find out that the ones they make go from 69-76. I know from looking at parts diagrams that the part #'s are different from earlier models, and that the '78 used a brake light switch underneath the m/c and bypassed the union block on the triple tree.
Or would it just be better to use an aftermarket m/c? Any thoughts would help. At some point, hope to add a dual disc.
Thanks
