Will these wheels fit on my car?

Howdy, I’m Alex and I’m new to the group, I just got my roadmaster last October and I’m looking for a set of wheels to maybe give me car a classic but sportier look (yeah I know it’s a roadmaster). Will these mid 60s 15” Buick rally wheels fit my car? I plan to restore the wheels, get white walls and put them on. Found that my local classic car graveyard!
