But there are original used tach’s that can be rebuilt better than NOS. More accurate and more reliable and durable. Even if it’s working now you’re taking a chance with sensitive electronics. Things corrode and deteriorate just sitting on a shelf.
The face can be repainted and silk screened to look fresh new. Not 50 years in a box new.
Know your part.... the rivets sometimes on rebuilt tachs can look off. BUT on 67-71 tachs the rivets are hidden. Also repro gauge needles can look off. Usually in the center of them... on these tachs the center is also hidden.
some people foolishly buy NOS parts cause they don’t know how or where to restore and rebuild used parts.
