The seat problems come in two categories:
1.) The floor pan that holds the front seat mounts cracks and allows the stud that secures the seat to pull out. I recommend that you take two L shaped pieces of 16 gauge steel and overlap the damage. Cut and fit one "L", drill the bolt hole and the weld a bolt in the hole that is for the missing stud. Then weld it in place. The repeat the cut and fit of the next "L" and weld it in place.
2.) The seat back frame cracks and splits. I riveted mine with some solid monel rivets. You can weld the frame if you don't a have a rivet gun and steel rivets. Removing the head rest is the difficult part. See http://forums.stangnet.com/showthread.php?t=478804&highlight=seat and you'll find pictures and instructions. Once the head rest is off, unzip the upholstery and slide it off the metal frame.

lol....yeah its either the floor where the front of the seat mounts is broke (which can be welded quickly and easily) or its the seat itself. It is just pop welds that hold that junk thing together. You can remove the upholstery and twist it back and hold it in place while someone welds it together. you will more than likely see both tears and broken pop welds in the metal.
