Ed,
Yes on the tinting, but also the general look...
I've got a friend who thinks his radio is original. But in several ways it doesn't look right --including the clearer Firebird look. I think the thing is a very nice repo. He's going to show it in a couple of weeks. (It looks and sounds great, so obviously, he does not want to rip it out!) Lucky for him I'm not juding that one!
I'm also on the look for one myself. (Right now, I've got an obvious repo.) At that same show, I'm going to stroll the swap and vendor aisles, looking for a bargain. In my case, it doesn't even matter if it works...
Thanks!
