Thank you very much.Motorcraft is Ford. Gates may be the supplier to Ford. In any case either brand is well known and reliable.
Thank you very much.rockauto.com lists brands I'm not familiar with...Melling and Cloyes. It says, "...Cloyes, the world leader in timing drive systems." Cloyes has the better warranty than Melling. If the Melling kit has what you need, and the Cloyes kit doesn't, the Melling will probably work great.
