Replacing Speedometer on Dash/Cluster

Many issues in the clusters you can repair, but probably "not so much" the speedo. Unfortunately, I've no idea where to take them anymore. In a previous life, I sold auto parts. Even little Spokane (Spokamentro) used to have a speedo / instrument shop.

I don't know 'bout 66, some of the older cars as well as the newer clusters with Ralley cluster (oil pressure) had the instrument regulator built INSIDE the fuel gauge. This is easily ID'd by having 3 studs on the rear of the gauge.

Other issues with printed circuit are broken connector pins and other corrosion issues, and ADD a ground pigtail to the cluster
