Tim, you might email or call Bill Mock. He is an old Corvette judge from Oklahoma that rebuilds water pumps and has a lot of the old clamps. I just bought several from him for my 69 Z and my 66 Chevelle SS big block car. He seems to really know his stuff and has been collecting them for years.Thanks for the tip Len, I ordered 4 wittek clamps from Bill Mock, 2 were nos from 1969. I also purchased a rebuilt water pump from him.. I spent a lot of time on the phone with him. Sounds like a great guy!
(918)333-0748 or (918)214-5206
You are welcome Mike, glad to help. Yes, Bill is a great guy with a lot of knowledge on the old water pumps and clamps.
