my 2 cents,
I had the same problem with 69 camaro console gauges I sold on ebay and was told they worked when I purchased box finds of stuff but the buyer said all the gauges were no good, what to do I paid for 2 new repop gauges and he paid for 2 repop gauges and now the problem is gone and again my 2 cents only is pay for half of the repair bill and remove that stress from your life.
