Upper belt pivot mount cont.
Pic 1, This is what I had for bar stock. It is a 1 1/4" wide channel with 3/16" walls. The seat belt pivot point bolt is a 7/16" fine thread. It fits perfectly into the channel.
Pic 2, This is the other side of the channel with the nut welded in place. Once in place, this piece extends above and below the double wall construction. It was clamped into place with the flat surface facing towards the inside of the cab. The pivot bolt is tightened against the inner surface of the pillar pulling the area around the bolt tight against the doubled metal, and this channel is plug welded through those holes mentioned earlier. For anything here to move, it has to pull the entire pillar and corner window structure with it.
Pic 3, Shows you a better view of the double thickness of the inner side of the pillar through the belt pivot bolt hole.
Pic 4 Shows a better view of the lower belt mounts (these are on the driver side). After the seat is mounted, these will be positioned on the floor with the nut plate welded to the floor from under the truck.


This was about the point where you take a breather, and sit back and look at the accomplishments so far. its time to review the "to do" list, and decide what order the remaining stuff needs t be done. At this point, anything done out of order will have to be taken apart to get the one thing you missed. This is also where you look for things that need to be corrected (there seems to always be something).

Yep, I found something.
