1969 Race Dart w/ 426 Hemi- garaged for 45+ years

Thanks, I was going to have the body shop add those. What do people use for them?
You`d have to ask these guys what they did, but I`d imagine what I`d do is flat washer welded to a bolt recessed into the top and glassed over with a tube sleeve covering the bolt, and washer lock nut on the bottom with minimal thread protrusion.
