That's interesting. I've never paid a lot of attention to the radiator hose clamps before, but sure didn't know worm gear clamps were used in that application, especially randomly.

All of the other hose clamp applications I have examined, have been marked "CANADA TRIDON ALL STAINLESS".

This is good info that will someday provide useful information for restorers. Keep it coming. =D>

Jerry,

I'll check my NCRS manual to see what they say about the clamps and report back.

That would be great. Thanks. IF I remember correctly, NCRS checked the hose clamps for the correct date stamping on C2's. So, I'm just drawing on that recollection & assuming the stampings on the ZR-1 clamps may be similarly important.

Any thoughts on the reasoning behind a single, odd clamp?
