I put an order in Clean air while hunting down some parts for a customer, and 2 out of the 3 parts are wrong, now I had to call my charge card to fight to get the money back. One part has a bad weld on a rusted out area someone tried to fix, and he still tried to sell it to me for almost $130! And it's the wrong part, he seems confused on parts for a 301 and a 400, when he had a conversation a year ago w/ a 78ta'er about the same part, and still is selling the parts for the wrong engine, he found a box of the 4 port valves, even though they are blue, they are for the 301, so be careful w/ this company.
