There are other companies out there that make direct bolt in kits for the 73-87 GM Trucks. They may cost a little more but will save you time and headaches over a universal make it fit kit.

Vintage Air offers an all electronic kit designed specifically for the 73-87 Chevy and GMC Trucks. The kit includes a new electronic control that goes into the stock location and will tie into all your existing vents if the truck had factory ac. The non factory air truck kits include the reproduction vents to go into the dash.

Just another option for you. www.vintageair.com
