Reply to "Changing out CMC Speedster Gauges"

Before trying to pull the gauges out into the cockpit:

Get a nice blanket and fold it up so it fits in the driver's foot well.

Lie down on your back with your face looking up under the dash and you'll be looking right up at the gauges.

Each gauge is held in place with a square, "U" shaped retainer held onto the back of the gauge with small, knurled, round brass nuts.  Spin those off (using your fingers should be enough) and remove the retainer from each gauge.  Now they will be loose so you can remove them from inside the cockpit.

As Greg mentioned, you should be able to pull the gauges out, but depending on how long the builder made the wires determines how far they can pull out.  You may need someone else to gently try pulling them out one at a time while you lie back under there to see which wire(s) hold the gauge in place and try to give them more slack.  

Eventually, you'll figure out what's going on and then can remove and label each wire, one at a time, to re-connect them to the new gauges.  I don't know if you have CMC "Classic" or "Vintage" gauges or a set of VDO 356 Reproduction gauges, but wiring to all of those should be in the "Resources>Library" section on the top menu bar at the top of this page under one of the CMC/Fiberfab build manuals.  If you can't find them, PM me and I'll send you a set.
