Early A shoulder belts?

When you weld your reinforcing plates to the trans tunnel, be sure to crawl under the car to verify that your newly installed seat belt bolts aren't too close to the driveshaft. When I added the 3 point belts to my Belvedere wagon, I welded a lock nut into a piece of 3/16 steel plate, and fished it up thru the door post between the front and back doors, and then welded thru the inside of the door post to attach the plate/nut. I used the stock seat belt bolt holes in the floor. It worked nice on that car, but I will have to do something different with the Barracuda shoulder belts.
