you have to modify the firewall by punching out the large section. i believe the non-a/c cars have the indentation. It kinda looks like a 'P' except turned to the left 90 degrees. Also, there are dimples where holes need to be made for vacuum hoses and a couple holes for the a/c box studs to come through and attach at the firewall.

i have done this entire conversion before on at least one car. it's best if you have a factory a/c car as a template to go by

I installed the factory air in my 67 Fastback years ago and the only problem I had was with the vacuum operated controls. I finally figured out that it needed a vacuum reservoir to have enough vacuum to operate the controls. You also need a check valve in the vacuum line so when you step on the accelerator you don't lose vacuum. Everything else just bolts up after you cut the sheet metal.
