Where is the “top of the metal on the dash?”
If you have the dash in the Bronco, that part gets covered by the dash pad. So there’s no good place to measure.
Here are some pics that should get you what you need. (And yes, the numbers are the same on both sides.)
22-3/8 from floor to cluster screw hole, and 16-15/16 from floor to edge bend on the dash.
Good luck!
