Has anyone removed gauge overlays? The 87 GT vert that we just bought for the wife has white overlays which aren't a problem....except.... a previous owner installed a 120 mph overlay over the 85 mph speedometer. I don't have experience working with these overlays and we aren't really in a position to just tear the gauge cluster out and start with it at the moment, just more curious as to how easy/hard it could be. I would like to retain the speedometer that is in the car vs replacing it, but dunno if we were to use an adhesive remover or anything like it if it would take the printed numbers from the original gauge face. I would think that they would at least fade? Anyway, does anyone have any experience that they could share some tips?
