This peel and stick Mopar 340 Four Barrel Air Cleaner Decal is an accurate reproduction of the original used on 1972 and 1973 models. Measuring approximately 10-5/8 inches long and 2-1/4 inches wide, it is identical to the original in every aspect of color, size and shape. Our Mopar Air Cleaner Decals make a great finishing touch to any engine rebuild or restoration project for your Chrysler, Dodge or Plymouth. Handy installation tip: If you try to put a decal like this one on dry, you may have trouble getting it positioned correctly and if you try to remove it to start over, you will destroy the decal. Instead, try mixing a tablespoon of Dawn or some other mild dish detergent per gallon of water and after mixing it up thoroughly, take some of the resulting foam and smear it all over the lid. Using the detergent foam this way will allow you to safely slide the decal around until you have it positioned correctly. Once you are satisfied, lay a piece of wax paper on top of the decal and squeegee out all of the bubbles. After the decal sits for about 24 hours, your air cleaner decal will look good as new!!!!! 1972 & 1973 MOPAR AIR CLEANER DECAL For The 340 Four Barrel Engine - NEW - Plymouth, Dodge & Others
