The outer door belt moldings on 1987-1993 Fox Body Mustangs are one of the areas that sees a lot of sun fade and damage due to the elements. The nice trim black color that these came with from the factory can quickly fade over the years from exposure to outdoor conditions. Replacing them is easy and we have a How To Install Mustang Roof Rail & Door Belt Molding guide to assist you on later 1988-1993 Mustangs, but for 1987-early 1988, you will have to drill a few holes and utilize the 1987-1993 Mustang Outer Door Belt Molding Hardware Kit. Today, we are going to show you how to do this.

As seen on this 1987 Mustang, the 1987-Early 1988 Fox Bodies featured square holes for the retainers.

Looking at the late 1988-1993 Mustangs, you can see that Ford switched over to the round discs, which are featured in the hardware kit that we offer.

If you have a 1987-1988 Mustang that has factory square retainer holes, you will need to drill out holes for the new hardware. What you will want to do is take a tape measure and measure from the center of the hole near the outermost edge of the door and make the following measurements:

  • 4 3/4"
  • 14 1/4"
  • 23 3/4"
  • 33 1/4"

Once you have these measurements, drill a hole small enough (1/8") for the rivets to slide into and install the new hardware. Be very diligent in centering the holes on the door so that the molding fits properly against the weatherstrip without gaps.

On the very first retainer (from back edge of door) the square hole is in the exact position that the round retainer needs to be. So for this one, you will need to position the hole slightly rearward or forward.  

Once installed, you should be able to install the new outer door belt moldings with ease.
