Gas tanks strap mount points

Hey guys,

I am getting ready to install new gas lines, and mount tank, is the attachment point for the straps roughly underneath the middle of the spare tire area. If so, I noticed that one of them is gone completely and is a hole there instead. Whats a good fix for that problem area? Do I need to have someone fab and spot weld a new one, or what are some other options? This is on a 1973 dodge dart sport 340.

Thanks
