Hello, I just recently purchased a 1977 XS 400 to restore for my son, the bike is fairly complete, however it is missing the front brake caliper. This is no longer an item I can get from Yamaha, so I am searching the used market for one. I just need some insight as to what year/Make /Model caliper will fit on it, in the stock location. I saw the other thread about swapping the rotor, I really don't want to go through all of that. Also in some of the photos, I have seen what looks to be a bracket, which I do not have either. If anyone has any suggestions of a good, reputable source for parts that would be awesome too.
