Factory A/C

[DDay1]

Today I acquired 2 complete factory A/C systems for a 61 Chevy. I want to put the best parts of the 2 systems on my 61 conv. Has anyone ever converted their car? I really need some detailed help. Are the holes in the firewall the same on A/C and non A/C cars and how tuff is this job? :confused:

DDay,
I have 61 that had factory AC. I think the AC cars have extra holes above heater box. See pic on my post firewall block off plates. Do you have pic of the parts you picked up. I neeed pic of the box that goes on firewall of AC cars.
Thanks .
