Thanks for all the tips. I'll try polishing the plastic part. As for the stereo, I'm just going to keep using my portable blue tooth for now. $99 each to recone the speakers, or $99 per pair for reproductions plus an adapter to fit the stock bracket (additional cost was not listed). Plus rebuild of the radio. If I keep the car, I'll do the custom auto sound like I did in the 1957. Fits the stock hole but operates like new. For now, I don't want to spend any additional on unnecessary items as my budget is already tight and IF I sell the car, the new owner may choose differently than I would.
