All Tamiya Porsche 956's are exactly the same save the plastic mold color. All of the Tamiya 962's are the same save the plastic mold color and wheel type. None of the 956's have the clear molded in. This is only on the 962's, and they all have it. None of these kits are particularly rare but they are getting harder to find. The Newman version is real easy as not many people want to deal with the yellow plastic.
