PO Hosed me... Whats the Fix?

[elks]

So I am picking up a hard top tomorrow. I need to get a top on my blazer for the winter. Soft top fell apart, its only like 8+ years old. Windows have all turned yellow and the cold this winter cracked em all.

At any rate looking across the front window frame, I have 1 of the 2 needed holes for the sunvisor braket on each side. Basically the one on the upper vertical section is there but the one on the lower angled part is gone. Looks like they welded over the hole and ground it close to flat.

If I am only running the top for the remaining winter can I run with just 1 bolt each side? Max speedo n my blazer is only 55 and most of its duty is coyote hunting. It will not see any real hardcore wheeling this winter.

Are there insert nuts? Can I weld a nut to a flat piece? I need something, but will one of the 2 kind of hold?

Thanks
