It's going to be a challenge to find those small gauges without buying the entire gauge cluster. And, even those have become scarce...and, pricey. Clusters with the Fuel Economizer gauge ('75-'77) instead of the tach are cheaper and will have these gauges...but, they still bring over $100 if you can find one. On the other hand, finding/buying (4) original individual gauges are going to cost all of that, anyway. Be advised, the flex circuit on the back of your instrument cluster is different than what is used on clusters with gauges.
