Our catalog record only ties this one to a single year, 1975, and it appears just once across the parts books we've got, so there isn't a lot of history to draw on beyond that. If you're matching this up to a bike, best to check the fit against what you've got before you order, since we don't have a broader run of years to point to.
Sorry if we got something wrong here. If you think this information isn't correct, .
