What are the differences between 65-66 and 67-73 Factory A/C

Hello,

Its an old post, but I have a new question from a new member. I am helping a buddy convert his '65 Valiant to factory A/C. With the help of the photos in this post and the measurements provided by 65 Dartman, a have a good template for the firewall. Would a member provide the final measurement I need, the distance from the upper edge of the large blower motor hole to the firewall pinch weld right above it? Thanks

i was no longer following this thread until Ulf @65dartcharger liked one of my posts. After I get home I can get any measurements you need as my project is still under construction with no components installed at the firewall.
