C2 By Pass and Expansion Tanks Hose Camps

[John F.]

I have an early 66 L79 Coupe that a previous owner frame off restored nicely, but with quite a few aftermarket parts. I am currently sorting through it and trying to correct judged parts as is practical. Right now I am fixated on hose clamps, specifically for the bypass hose and the expansion tank hoses. Between the Tech Board & Archives, TIMJG and AIM, a couple of experienced judges, sellers of alleged correct parts, and photos of supposed original cars, I am confused on correct clamps and which ones had what specific screw/screw head. Has there ever been a technical article or survey of C2 hose clamps that I'm missing?

Can anyone offer difinitive insight into the correct brand and stamped # for the hose clamps and the correct screws/head types for the L79 bypass hose, the Expansion Tank short hose to the heater hose T (pn 111607), and the balance hose (pn 274337)? Which slotted fillister head clamps screws should have the washer/shouldered heads?

Thanks
