Patching Dash, Heater Box

Showing the metal patching on both the dash and the heater box. The dash had seven extra holes that have been patch welded. And the heater box had a rectangular cut out where the two heater core pipes come out of the top. With the patch in place, the two holes need to be rebored. I don't know where they need to go exactly, so I'll need to get some dimensions or a heater core to get the measurements.
