Cliff Ruggles is the Best Q Jet parts/ rebuilder I've found, all his kits are made for Alcohol in our gas, all you need is your carb number, I recently ordered the big kit for a Q Jet, he had everything, plus stocks other parts as well, like I needed a missing Vac tree, Pulloffs, and the stud for the aircleaner, quality parts if you need any.
