This vintage '67 Mustang only came with lap belts in both the front and rear.  The extra added protection of a shoulder strap will always be welcome in an accident.

	The seat belt kit.  Only one front and one rear seatbelt assembly is shown.  the parts on the left half of the photo are for the front seats.
We removed the front seats for this because we thought it would make it easier to move around the inside of the car.
	You can immediately remove the old seat belts and put the new center belts in because they use the original factory holes.
Next we measure for the upper bolt. We then center punched the hole and drilled it.  This top bracket also requires two pop rivets for each side.
	Center punching...
Drilling... We worked up the drill size in three steps rather than jump straight to the big one.
	Drill for the bottom bolt which holds the inertia reel next.  Cutting the carpet where you want to drill is a good idea so that your drill does not get caught on the fabric.  Attach one of the ninety degree brackets to the reel and then use the bracket and another bolt to attach it to the floor. Use the larger washer for the underside of the car.

	Tighten the bolts for both the upper and lower holes with a ratchet and you're done.

One happy driver! The new belts work great and feel "right".
