Also look at the needles of the service parts but they look to be silver as well. Interesting..
Gary (69Z28-RS) is there any ink stampings on either your original gauges or the ones you bought at the swap meet?
As for cleaning I would use q-tips and alcohol. But not on the printed surfaces. Just soapy water & q's for that. Just make sure to get all the water out or it can cause damage to the windings on the gauges long term.
Anyone else out there that has ORIGINAL gauges take a pic of the faces? Doesnt matter at this point if they are still in the car or not. I want to know if the brushed look or painted/coated look was interchanging.. Meaning more than one supplier.
Ill have to look in the X33 & L78 cars to see how their faces are now.. Hmmmmm
