I'm looking to reinstall a factory radio in my 70 GS. Unfortunately, one of the mounting rod's nut is stuck: it looks like the threading is bad and the rod/nut is unusable. Anyone know if this small rod is reproed? I'm looking AMK and I see some things that are similar but I'd like to be certain. Same with the nut. If I'm not describing the rod well, it's one of the two in the bottom, front which attaches to the dash.
