Gmc v6 hose clamps
 

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.

Thanks Jake , yes, I've seen the reproductions . Still trying to find the originals that are stamped A11. These do not match in the plating color Im looking for either. Im picky , :lol:

Re: Gmc v6 hose clamps wanted to buy
 

Did you find the A11 clamps yet?

Re: Gmc v6 hose clamps wanted to buy
 

No , found A 10 1/2 and A12 but no A11

Re: Gmc v6 hose clamps wanted to buy
 

Go to part target dot com and type in A11 in the upper right hand corner and hit search. Find the "Clamp, Hose" on the selection of A11 part numbers and click the number linked beside it. It will give you some specs and dimensions and the OEM supplier and most importantly a National Stock Number (NSN). In some cases there will be a photo. If the A11 you need is a match you can probably find military surplus by looking around with the NSN, or even contact the OEM supplier if they are still around. This one has a bunch of suppliers including GM and other part numbers that you can search too. I have found stuff this way pretty easily. Note that parts made for the gov't are made to spec. Surplus parts from different suppliers may look different but they do the same job, so get a photo before you buy if looks are important to you.
