This is an opened single din dash kit made by metra to fit a 1989-1992 Volvo 700 dash.
Metra part # 99-9200
You will need this dash kit to install a single in into that vehicle.

This dash kit also works on some ford pickup dashes from the 60s and or 70s. You can put this dash kit in upside down and it fits that ford pickup perfectly. Good old installer trick from me to you.
