I had to take out the kick panel and two heater vent hoses to access the speedo cable connection behind the
instrument panel (required pinching action by two fingers to get the cable to release from directly behind the
instrument panel - it was not an electronic connection as some thought). I could touch the cable release
mechanism with one finger, but the second hose blocked full access. Once the second hose was removed, it
was easy (well, in a convoluted, arm twisting way being upside down in the driver's seat at night in 10 degree
temperatures with cold fingers) to reach the back of the panel and release the speedo cable and then pull out
the instrument panel. Replacing the lights was the easiest part (did all of them while I had the panel out).
Thanks to all who made suggestions.
