Weld nuts

Need 2 weld nuts for 72 Demon to mount Radiator. I know they take 1/4" bolts but the smallest I could find is 5/16".
Make some. Flat stock, drill, tap. A little grinding and there you go.
@Dana67Dart beat me to it. Dude, these would be SO easy to make. I am thinking I could make a pair of them in 15 minutes. Do you have a drill, drill bits and a tap and die set? You can do it easily.....
