Walls Are Twice as Thick as Original GM Part# 3963756
Question: What do you get when you mix thin gauge plastic with radical temperature shifts from hot to cold and back again? Answer: Warping and cracking!
In the auto restoration industry, there has been a history of scrapping OEM air conditioning ductwork in vintage ’70-’72 Chevelle, Monte Carlo and El Camino models because the duct had snapped off flimsy mounts, or developed cracks. So our engineers decided to develop our own replacement duct and while we were at it, figured we could address the hot/cold warping issue head-on.
Classic Auto Air’s model-specific Perfect Fit ELITE™air conditioning system is now available for 1970-72 Chevrolet Chevelles and El Caminos. You can now retrofit an original 1970-72 Chevelle/El Camino with modern performing air conditioning, heating and defrost.
