WI Gmc v6 hose clamps wanted to buy - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**60-66** · 04-08-2021, 10:05 AM

Im restoring a 1966 GMC and looking for a specific hose clamp for the upper radiator hose. It will be stamped "A11" for the top hose. I've found the A12s NOS for the lower hose. Looking for very nice used A11 or NOS would be great. Looking for a source from all you GMC diehards ! These were ONLY used on all GMCs from 1960-1966, not Chevy, but may have been used on other brands like Ford .

So do they have to say A11 etc. on them?
Also maybe Mac's has them? - https://www.macsautoparts.com/model-...8-24617-1.html
Or maybe Jim Carter - http://www.oldchevytrucks.com/cart/p...1&i=10293|||||

Yes , that's what I'm after, A11 stamped clamps. I've gone through Macs and the others . Very frustrating that they don't give the clamp size for the hose their clamp is suppose to fit on their sites. But if all else fails , repro will do till I find NOS. This truck is getting little to nothing aftermarket so I've probably made it a bigger challenge than it needs to be , but I've had pretty good success so far. Thanks for your help !!

Appreciate all the help RocknRod. I have been searching ebay but looks like I missed a few. I have been looking at some of these that are close in size. I bought a few. Actually found 6 A10 1/2 clamps but waiting to get them to try. Thanks again for the efforts !!

60-66, with limited knowledge on vintage hose clamps, it seems that certain Ford vehicles used these type of clamps too, as you mentioned.
