Thanks Jason! I figured out how to get the strips out last night. Your pictures will help anyone else who is looking for this info. I turned the oven on very low, removed all the components from the cluster housing and placed the housing in the oven for a few minutes. The adhesive for the bottom felt warmed up enough that it could be easily peeled back to access the idiot light strips. This method allowed me to put the felt back in place without damaging it or messing up the adhesive.

I might add that I painted my old needles with L'Oreal "L'Orange" 410 nail polish but it is a little too red and makes the needles hard to see in low light. I will search for a more neon orange paint and re-paint them. I also need a flat paint to reduce the glare on the needles.

The oil/gas/temp cluster from the gas car does not seem to work well on a Diesel. No temp reading, no lights, fuel gauge seems off and the empty light is lit with 1/2 tank, GP light stays on all the time. The wiring must be different for the gasser. I guess I'll have to use the Diesel one and hack in the efficiency gauge and face.
