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

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…
