Vintage Air question on a 67 Camaro

[1sick67]

Hopefully this is simple and someone has actually installed this so i can know for sure. My car didn't originally have any A/C stuff at all. I know i have to replace the center dash cover with the A/C style but does the complete Gen IV kit also use the astro vents on the outside part of the dash? Because if so, i think i'll need to work on that too.

Thank
