Do you remember what years they did fit? I ask as the frames on all but the 77/78 were the same. So if it fits a 69, it will fit a 72. If it fits a 76, it will fit a 72. I think even if it fits a 77/78, it will fit the 72 as the main frame was the same I think except for the neck.
The ride IS the adventure. The destination is just to get gas!
