Help needed! Stock drum? studs on drum? off of different car? 1972 swinger

Thats what i want confirmation on. If that ssbc kit would go for these rims i would still look into buying that kit since there isnt many if any honestly that fit those rims. Anyway If i do end up needing new rims and ones i can use the stock hubcaps on hopefully, i would be open for suggestions on that too. I would like to possibly be able to use my current tires on the new rims though wanna try and stay on 14 inch.
so from the pictures it looks like you have 9 inch drums? SSBC makes a kit that bolts onto the 9 inch spindles. As long as you have 14 inch rims, they clear those discs

Yeah but does the hub bore on the factory 14” drum wheels work on those hubs?

Nevermind that SSBC went out of business and was resurrected again recently. Doesn’t give a warm fuzzy feeling for finding replacement parts in 10 years…
