Just picked up a 1973 XL70 in overall very good shape but I know I'm going to need some parts for it and I'm not sure where to look. The one thing I'm not sure about is the chrome piece on the rear that the turn signals attach to. One of the turn signal mounts is busted off but the other side is in good shape. Should I just have a tab welded on or find a used one? I'l also need an exhaust because it's kind of hacked up and I want to replace it and put the old one on my z50. The other parts I need should be shared between a bunch of bikes- turn signal housing, clutch lever, possible clutch linkage parts cause under that little cover is kind of rusty, bushings for the taillight bracket, seat cover, airbox parts, etc
