Think Installers will be more likely to question a 60 year old rim that is riveted, rusted, pitted in the bead seal area, likely could be bent, originally set up for tubes. Even an restored rim might generate more scrutiny.
Yep, and the old question of whether to use tubes in tubeless tires on tube rims that don't have the bead lock drives a lot of us crazy.
Since the truck is 7/16" studs and the wheels are 1/2" holes wide burge lug nuts are the best solution to center things up.
Would you have a link for those nuts? I measure the lug holes on my stock rims at 9/16 and they seem ok with regular lug nuts.
