Cold here so time to get back into the shop and work on the Truck. I had these belts so started by welding blind nuts on the back side to ease the installation.
I moved the belt body around until I could use the double plate as a mounting point,
this is behind the front wheels underneath.
I placed the belts in the opening behind the seats, had to do a little adjustment to the inside wall but nothing extreme.
Next I wanted to reinforce the rear door pillar as this would be the pivot point and take the most stress in the event a crash were to occur.
