Wiring Harness GM Part Number Trace

[spentzos]

Hello,

I have a 1967 K20 with a bad wiring harness. It has been piecemealed over the years. I have found a new NOS part. I was told it was for a 1968 (not sure if 67 and 68 are the same). The box states: Wire Assembly Gr. 2.480 1 #8904672. Can anyone please tell me what year this part is for? Also, is it for a basic or full gauge dash cluster?

I called the local dealership parts department and they stated their parts numbering only went back to 1976.

Any help would be appreciated.

Thanks.
