Rubber Floor Mat Retainer Studs

I've been repairing the rusted floor on my '66, and several of the Rubber Floor Mat Retainer Studs are rusted too badly to re-use on the patch panels. Has anyone found something that can be used as a suitable replacement?

It looks like the originals may have been swaged in place. I don't have access to a lathe to make these, so I'm looking for something similar in size and shape that could be welded on the patch panels, perhaps from the back side.

Thanks!
