Dale's Cuda Shop wire hose clamps not the correct size? - 1967 Dart 273

For the record when I reference 1 1/2 or 1 3/4 I'm referencing the approximate size. When ordering clamps if you order a 1 1/2 it might be too small. For some reason the way they are labeled doesn't seem to have any corolation to the size that will work.

Example is the clamps I ordered for the by pass hose. The hose measured 1.1" od and a " 1 1/8" " clamp worked.

I bought a range of clamps to try.
