Vintage Air or Classic Air on 71 R/T

Hello, I'm restoring a 71 Charger with a pro - touring theme. Originally it was a non air conditioning car. Evidently there's two different air condition boxes to choose from, basically big and small. Had anybody converted a 71 B-body to air conditioning and which kit/box did you choose? Thanks

I'm also interested in this. I installed Vintage air kits in a 69 Camaro and 77 Chevy pick-up. I'm not very impressed with the ducting and controls. I will be putting a kit in my 68 Charger and would like to hear from others who have tried other kits.
