Hold on a second, Howard. My research doesn't indicate that P/N 473183 was wire type clamp - only that the spring wire type replaces it.

It's entirely possible that they went from spring wire clamps (as shown in shop manual) to band type clamps (as shown in the AC install), but as supplies became exhausted, they went back to spring wire (as shown by the superseding part number).

Meanwhile, either the 55-56 parts book counts per application are off or there's an application listing missing that never got corrected. However, if you look at the 48-54 parts book (Gr. 11.0122) you'll find that only one band type clamp (P/N 230085) was used (at the water pump inlet) on the 51-54 models; the rest (five) were spring wire clamps (P/N 462013). Seems to me that the V8 usage would follow similarly, then.

All that aside, clamps are clamps; if there was a significantly problem of functionality with one over the other, I suspect they would have said so in a bulletin.

We're only trying to define what's acceptable, here. It's entirely possible that use of either type (in sets, together with one of P/N 230085) will be correct.

Again, one would need to find an engineering drawing of P/N 473183 to verify its type - beyond the shadow of a reasonable doubt.
