1966 dart A/C setup in a non A/C car help wanted

I am about to undertake this in a 1966 valiant. I have all the under dash parts except the gas peddle. I was going to use more modern parts for under the hood.

The question I have: Did you need to move the electrical bulk head connector?

I was because I was told that this would need to be done to add room for the under dash box.
