On the shoulder bolts for the three point seat belts.
I used a flange washer, then extended the flange with two SAE washers, then I added a piece that I made out of those connectors for threaded rod. The connector is hex shaped, threaded and is about an inch long. I placed it in my drill and then ran it up against the grinding wheel to flatten out all of the corners. Then cut it down to about a third of an inch with a dremmel tool. Glommed on the JB Weld and screwed down the threaded piece. Then some paint.
