97 tahoe seat

I have a 1997 2 door tahoe sport with leather seats and the works, but the other day i noticed that my seat was loose and it is the bracket on the outside o the drivers side is broke, what would this peice be called n where can i get it?

Both my 97 tahoe and 92 blazer had the same problem. There is a bolt that is welded to the seat frame. the "seat" screws into that screw and its pulled through. I neded up taking pieces of meta and putting over the hole and re-tighten the seat up. In my 92 I had the lower sean mount replaced after both sides pulled through.
