Any way to add A/C to 1967-1972 truck without cutting holes in firewall or dash? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Every once in a while I think about wanting A/C in my 1968 Chevy short bed fleetside. But the thought of cutting the firewall or the dash prevents me from doing it. My truck never had A/C from the factory but it does have factory 396 with 400 turbo transmission with black paint and red interior.

You might consider an under dash unit? I once had a '72 Blazer (which I should have kept, LOL) that had an under dash unit. Don't remember the brand but it did a good job cooling. Would think such a unit would do even better in the smaller confines of a pickup cab. Would only require a drain line and the coolant lines thru the firewall.

.

I once had an under dash unit in a '68. Sourced all the parts from salvage and had it going for just a few hundred bucks.

That thing would freeze me out of the cab.

Ran the drain through the rust hole in the floor LOL

You'll still need to make holes in the firewall for an underdash unit for the stuff to get to the compressor. I think Vinatge air or someone makes a vent panel that puts the AC vents under the dash so no need to cut there. With most of Today's aftermarket AC, the firewall is cut no more than what you would for an underdash unit.

This is the only way I know of adding A/C without cutting the dash or firewall.

Agree, nice looking steering wheel. Thinking that is most likely from a mid-60s Chevelle possibly a 64 or 65?

It is a steering wheel out of a 1965 Chevelle/El Camino. I watched a few YouTube videos on steering wheel restorations and thought I would give it a...spin.

Found it in eBay for cheap.

Vintage Air and Old Air kits use a panel in place of the heater core. The heater hoses and AC hoses go through the panel. No firewall cutting required. On the inside you can use their left, right, and center under-dash vents. No dash cutting required.
