Factory style hose clamps

This is on my 67 Dart 273 (cast iron WP) with Spring Wire Clamps.

I bought a set of wire clamps from Classic Ind and a set from Dales Cuda Shop (turns out to be the same set DCS sticker and all on both) What I found is the heater ones worked perfect, the by-pass was way too large, two of the radiator hose clamps were the correct size and two were too large. (My understanding is that the clamps are the correct size for the OE but the hoses that are available today are not OE OD size)

With 2 sets I used the radiator hose clamps that fit from both kits, the heater hose from one kit and bought from McMaster Carr a bag of 25 of the correct size for the by-pass hose.

I expected there to be leaks all over especially on the corroded fittings but not a drop. This is the first cooling system I have ever had that did not seep and it has the 16 lb cap!

Here is a post I did regarding sizes etc post #19 has PN for McMaster Carr clamp (I have a about 20 extra if anyone needs some)
