Re: Keep Your Cool! Vintage Air Sure Fit Install in a 67 C-10
Using a 1/4-20x2" bolt and nut with a 13/32x1" steel spacer on the backside of the A/C unit, you can bolt the left side of the unit down. The bolt uses an existing hole near the middle of the firewall from the heater unit. Once the underdash bolt is in, it's obvious where the left side bolt needs to go.
This is where a helper comes in handy. It's hard to be inside the cab and under the hood to tighten a bolt.
