70-72 expansion tank to radiator hose clamps

[Mike E.]

I know from the new JG that it should be a pair if side-screw clamps on the pressure hose from the expansion tank to the radiator. I assume they are Wittek because everything in that vintage was. My question: what size designation is stamped on it, if there is a size stamping?

Thanks, Rich. What was the original finish on the strap, as well as on the screw and nut? I have a couple of 2's and 23's, and they look a lot like yours with a charcoal/gray type finish.

Mike, no problem. If I remember correctly the original clamps were galvanized and the screw and square nut are zinc.
