65 Barracuda hub advice

I’ve been restoring a 65 barracuda for the past few months and I’ve hit a road block. 3 of my 5 lug nuts on my driver side front tire were removed while I was out. I didn’t notice before I went out for a drive, which destroyed my rim and my wheel hub (All 5 holes are ovals and my wheel studs just swing around freely in these holes). I’ve called every large car parts store and no one seems to have a 5 x 4” wheel hub that fits my car. I’m at the point where I’m considering filling in the existing holes with my welder and drilling new ones. I’d appreciate any advice you have. Thanks
