FIREWALL A/C TO NON A/C HELP

I did it without a firewall section on my
69 Dart. Previous owner installed the A/C box on a non A/C car and did not do any of the under hood stuff. I wanted it back to factory.
Welded up the stud holes, patched the A/C line holes and blower motor hole. Drilled out the new hole for the blower motor after the patch was welded in.
