Autozone or Napa Echlin, Quality?

Most large chain store parts come frome the SAME source and are packaged differently. Too many stories about the counter jocks lack of knowledge about parts, all major stores use a computer system and you get what you ask for. If the parts are not listed in the computer, stores have catalogs where the parts can be researched manually and special ordered. Its a good practice to call at least three stores to compare prices, Autozone can sell cheaper because they order larger quanties and have a larger discount structure. Kragen-O'reilleys is next then Probably Pep Boys. NAPA stores are generally franchises and cannot discount as much as others, NAPA also uses a GM refurbisher for used parts (so do the others just less). Always give the Chrysler dealer a shot especially if you have the part or casting number available. Rockauto.com is an excellent source for older cars, they have various sources for the same part and will identify he manufacturer. Buy American if at all possible we need the jobs.
