That's great for 1959!
What modern car or truck use riveted shoes?
I give you a clue? NONE!
I do lots of old car work and no re-builder will warranty riveted shoes only bonded ones.
In fact the outfit I now use will install rivets in addition to bonding the linings but it's only for looks and to match original.
Rivets were ONLY used when the linings needed to be replaced in the field using basic hand tools. Those days are long gone!
