Thread: Modifying or updating a stock instrument cluster

Tweet

I did what you're talking about on the dash pictured below. Instead of buying a full gauge unit I ordered a set from Classic Instrument (less speedo) without bezels and glass because the panel had a full face glass behind the dash face. This was a few years ago when Classic was still in the hands of the original owner up here in the NW. They've since changed hands, so don't know if they'll do that still. Might be worth a check.

The configuration of this panel supported round gauge shapes and the Classics were only slightly larger than the stock ones in diameter, so it worked out well for "peaking" through the openings. So you'll want to measure the available gauge design for those factors. In my case the gauge "guts" had to be fitted to a full width "can" that held the original gauge mechanisms. The Classics while being a good fit on the face, were much deeper, so I had to locate and drill holes through the original back housing to accommodate. I then put a strong but pliable (in case I ever have to service a gauge) sealant/adhesive around the gauge housing/hole to both hold the gauge in place and seal against dust and dirt intrusion. After that it was just hook up the gauges with the supplied sensors/wiring diagram and ta dah!
