Came across this listing...

I've yet to have first-hand experience with brake pads, but after going through my service manual, the items pictured don't look right...they look like disc brake pads. Pardon my ignorance if they ARE correct. Seller claims photo represents actual item.

If they are the correct item, is $25 a good deal? (Seller claims they fit '64-'69 as he says his catalogue only goes back to '64.)

ZW,
If your Riviera is still wearing it's stock drum brakes then these are NOT correct. Sometimes an aftermarket parts manufacturer just plain gets it wrong with a part number and proper application. 64 to 69 Riviera's did use the same brake shoes, I believe and 69's did have optional disc brakes, so this might have been the issue with the mix up. I have little to no experience with the second generation cars, so I hope someone else wades in about if the pads are correct for the disc brake equipped cars.
Take Care,
Tim

Thanks, Tim...suspicion confirmed!
