1987 Digital Gauges decoding?

[GNXJEFF]

I just bought a 1987 GN with the red aftermarket dash in it. How do I tell if my car came with digital or standard gauges? Thanks, Jeff

If your car has it's origional trunk lid, look at the rpo sticker. If it was a Digital Dash it will have a U52 in the list of options.
