That new dial scale looks great, Ron!   That's exactly how I installed mine. Yes, using pop rivets is a more permanent way of attaching it, but you really shouldn't have to take it off again. If the bulb goes, it comes out from the backside.

I just wish RD's repro dial scales weren't embossed like that, with the lettering raised. But hey, that's just a minor thing. Certainly better than not having any or a badly faded, darkened original scale.

Yes, you probably could try polishing the (once was) clear dial cover. I actually tried that on mine, but it never got very clear and the yellowed hue still remained. You're better off to bite the bullet and buy a new one. It will only enhance the eye candy of the new dial scale, bright white dial back plate, and LED bulb. You won't regret it...especially enjoying the radio in a darkened room at night!
