63 Clamps for Rubber hose from air cleaner to injection

[Bob H.]

Hi. I found the GM part number for the clamps but what is the wording on the clamp itself? Thanks

Hi Bob, I have several NOS straps but with the hex head bolt instead of the original pan head bolt. They do read 'wittek mfg co, chicago usa 20, straptight' . These would be 'service replacement' for judging purposes. I see these for sale on ebay for hundreds of dollars! Originals had the pan head bolt and dark lines running length wise for mfr process. Don Hooper has some real ones. The repros are much closer than the service replacement ones in details. Regards,
Dan
