I decided that I wanted the car to be as safe as possible for my family of four, so three point seat belts were a must.  As it turned out, adding these belts to the car was far easier that I imagined it would be. 

Front Seats:

On the four door cars, the holes for the retractor and the third point above your shoulder are already in the b-pillar, in the perfect spots, under the existing upholstery.  What could be simpler?  All I had to do was bolt them in. 

The top mount was a bit tricky, in that there is no way to get a wrench in to tighten the nut inside the pillar.  My solution was to weld the nut to a steel plate that just fit through the rectangular hole in the top of the pillar.  I hung the plate on a wire down the hole and then screwed the bolt in place.  After a few minutes of fumbling it went right together.  The plate also acts a a big washer to prevent the nut from pulling through in a collision. 

The bottom mount for the retractor is a simple bolt on, since the bolt hole in the pillar goes into the lower hinge pocket, and it is easy to get a wrench in to tighten it.

The buckle belt that is in the seat simply bolts through the floor with large washers to prevent pull-through.

The only problem I have found is that the depth of the retractor prevents the seat from moving all the way back.  This may be an issue for taller folks, but isn't for me, since it works with the seat where I normally have it.

The rear seat shoulder belts were just as easy to install as the fronts.  The retractor is mounted in the trunk, and runs up through the package tray, down over the seat, and bolts to the floor near the side of the seat.  The third point bolts to the package tray from the bottom, keeping the belt from rubbing on the package tray metal.

I have narrowed down my selection of upholstery fabric for the interior.  These samples are from Lebaron/Bonney.  I bought a sample kit from Lebaron/Bonney, which included all of their fabrics, leathers, vinyls, headlining, windlace, and carpet.  The kit was a very handy way to select a complete color scheme for the car.  Let me know what you think of the choices. 

I have chosen a scheme that is a bit different from the original, it will be a two tone layout with wool broadcloth and vinyl.  The body of the seats will be the wool, and the top 1/4 or so of the seat back will be the vinyl, and well as the leading edge of the seat bottom.

EDIT:  I have not ordered these fabrics, which were chosen for the project in 2001.  Since that time, I have looked at many fabrics, and will most likely not use the fabrics from Lebaron Bonney, but something similar available locally.
