Firewall heater hole for aftermarket A/C? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

70 C10 1/2ton
It originally just had a simple heater with no A/C. I am likely going to be installing an aftermarket AC heat combo kit (vintage or old air) and I am wondering how these kits incorporate the stock holes on the passenger side of the firewall. I am asking now so I don’t have to back track down the road when this truck is in primer or paint.
Any input is appreciated. Thanks.
