Vintage Air Gen IV install in 1968 Barracuda convertible.
I overlooked mentioning the insulating I did to the car to help with the noise, heat and fumes. Amazon sells Dynamat Extreme with free shipping for about half the retail price, and the blankets of aluminum foil covered insulating material are available for a very reasonable price at Speedway Motors. Using the combination of the butyl rubber Dynamat and the blankets of foil covered insulation together make for a cost effective and extremely useful insulating combination.
The blankets of the foil insulation can be cut to fit and taped together with that aluminum duct tape that has the wax paper on it to stop it from sticking to the wrong surface. Once its taped, it is almost invisible on the aluminum blanket. Carefully installed, it seals out an incredible amount of heat, fumes and reduces a lot of noise. Dramatically more than the Dynamat can by itself. Its important to think of these two materials as a system that works much better when installed as a package.
Once I finish with the dash work, I'll fully seal the remainder of the underdash, floor and side-panels with the aluminum covered blanket material and seal it to the car with the aluminum duct sealing tape. If the car you are working on is not a convertible, consider insulating under the headliner, as that helps tremendously too.
