Looking for information on how to identify an original 67 GTX / Coronet 440 air cleaner. Looking around on the net, it looks like there is no cut and dried answer. I have a dual snorkel unit that has the 13 ribs on the lid, and a nipple for a breather hose to connect to. The lid measures 3-1/2 inches high. Is this a correct unit for a 67? Looks like this one. http://www.nicksgarage.com/aircleaner/67_440ds_04.jpg
