Clean build.
On your dash pad I ordered a repo replacment one from Classic and could on get only 3 of the nuts to start, the studs were 1/4" shorter than the originals.
Called Classic and they said "Yeah alot of people had a problem with that, the manufacture said to sand down the bottom side of the dash until it fits".
If your original dash is nice, I would clean it up and use a quality vynal paint on it.
