Does anyone have a good source of a stock radio antenna for a '69 Sprite IV? Mine was loose. I was able to tighten it, and then it loosened again. When I tightened it a second time, I felt that wonderful stripped threads feeling. Now the antenna is flopping all over the place. There are two small screws on the mast, that might help me repair the antenna mast, but these are completely frozen. The only way to get them out is to drill them out. I will do that, but I wanted to have another antenna on hand just in case my surgery attempt failed. Right now, I have the antenna jerry-rigged with duct tape under the fender to hold it at a reasonably straight angle, and if it does flop, it flops towards the windscreen. I've checked the usual suspects for an antenna (Moss, BPNW, etc.) but no one seems to carry one.
