Dart Rallye Dash Questions paint/after mkt tach install

A couple questions about the 71 Dart, Demon rallye dash.

1. My plastic bezel has what looks to be a black tape/sticker in the blacked out areas of the dash bezel and the silver looks to be paint. Is this tape original? if not I still plan to remove the sticker and strip the paint using bleach white, what is a good black and silver paint to match mopars colors to look original.

2. My dash has the tach delete, I plan to install an aftermarket into the dash. it looks as if this would be possible without any serious mods as in cutting up the bezel which I hope to keep original. has anyone out there done this? pics would be great! Im thinking one of those little sun-pro tachs would work well.

Once the dash is complete I will share some pics!

thanks all!
