YH4 would be an option package ....the 1976 olympic editions were ZE2

Usually it designated specific color and stripe package ....

GM often used various RPOs for marketing packages/special editions ...they would send out a sheet to the dealers and it would offer a "Special Edition" with certain mandatory options for a package price.
