'70 Road Runner steering column support brace holes

[wwheel]

I cannot remember what these holes are for. Circled in orange. Just about to install dash in the car and would sure like to know before it is too late. The one on the left is threaded and the one on the rights is just a slot. Any help and or pics would be greatly appreciated.

Thank you!

The one on the left is threaded...

A long 'rod-brace' runs from the threaded holes down to the lower driver-side dash mount/pivot on my '69 Satellite rag. Pic early in disassembly.

For what it's worth.
