Milton,
I believe that for judging purposes, tower clamps are needed for the radiator hoses. The heater hose clamps are those regular spring clamps. If you look through the Buick Chassis Manual, you can spot some illustrations of both the radiator hose tower clamps and heater hose spring clamps. Sorry, I don't know the proper name for those spring clamps. They can be bought at most hardware stores however. Later today, I'll look through the rest of my literature to see if I can find any Buick factory photos or illustrations. If I find anything, I will post it.
