Recently acquired a 79 Sportster. It as called a little bit of everything from a Ironhead to a Flarhead. And, why is it hard to find parts/accesories? So many things will fit all models except the 79 Sportster.
Welcome Tenebre! Hope you stay around a while and get some good posts in. 1979 was a good year, but had some unique things happen...new frame, disc brakes and it is 30 years young...
I ended up milling out a tool to remove and install the neck bearings for my 76 and 79 xr750's. And did a convertion for some heavy duty ceramic bearings.
NHH...Welcome to HDTimeline, hope you get a chance to review some of the tabs at the top for self help and search tools. Too bad you did not get pictures, that would have been a great read I am sure.
If your looking for Obsolete parts for HD's. There is a shop in Rutland, Vermont named C&D Choppers. The owner has all kinds of NOS parts for just about anything.
