Is there really a difference between the big after market companies (NAPA, AZ, CQ, etc)? I am asking because I need new rockers, and AZ, where I work, has Melling kits for $28 each, and NAPA has the Clevite kits for $25 each. If there is no difference, then I'll go with AZ since I can get a discount, but of not then I'll go with NAPA.
