Further
"The 427 S/C gauge set is an exact exterior reproduction of the originals. The 180 mph reverse Speedo and the Tach come in 4" dia, with all Sub-gauges measuring 2" dia, as per the originals.
The FIA gauges also are an exact reproduction and are a direct replacement set for the SW's. The FIA's 160 mph Speedo measures 3-3/8", as does the Tach, all Sub-gauges measure 2-5/8" as per the originals."
They are nice looking knockoffs of the originals used. They are reliable in that they are Autometer...But they are mechanicals..not many are comfortable with bourdon tubes and lines filled with motor oil etc in the dashboard. They are truly smith like.
I have to order some up as well, just a matter of getting the best deal
