I think you will find a bracket on the underside of the fender. There should be a nut welded on the bracket where that hole is. These were for the early front seat belts and very common to rust. I have two 62s the early one is just a tub and didn't have the bracket. My later 62 does but doesn't have as much rust. When you do your body work it's best to remove the bracket for the repairs then spot weld back in. Keep it washed out and dry and should last a long time.
X2. check out my build to get a heads up on what you are in for.

The seat belt brackets start at #53 and then there is a little more info spread over the next couple of pages.
Keep up the good work.
