content: The add says it will fit stock CJs - with modification required if there is factory AC. NOT THE WHOLE STORY! It turns out it also needs significant modification with stock heater/air plenum in the 79 CJ7. Called seller & they said I would have to cut the enclosure (it's sealed) to fit. I'm certain that if I do that I will get whistles and other issues once the speakers start to move in the enclosure. I'm going with just the "Mod Pod" under-door enclosures (same manufacturer) and live with whatever sound I get from those. I returned the Centra Pods.
