The lug bolts are easy enough to use if the locating pin is in place. I
swing the drum to where the pin is
at the 12-O'clock position and hang the wheel on it, stick a bolt in at the
10 or 2 spot and start the threads
to secure, then fill in the rest. Too easy. Buick used the
bolts at least through 60 as well.
One reason might be production costs ? The loose bolts did not
require the press-assembly step to make,
cutting one process out of the overall production schedule.

From my experience the ‘50’s Dodges I’ve worked on had lug nuts, the
DeSotos and Plymouths had lug bolts and a guide pin. The studs and lug nuts
are a lot easier to put a wheel on, don’t know why they ever used lug
bolts. Never seen a car with mixed drums; if someone has that
setup maybe some drums were switched or possibly the whole axle.
