So if you lose the circuit board then can you lose the plastic backing altogether? Say you use 1/8" sheet aluminum or 1/4" plastic/Lexan. Something sturdy enough the hold the guages. Do the 4 corner screws line up with the metal dash or with the plastic backing? I'd guess the speedometer might need a fabbed support since it has a cable connection.
The shift indicator could be a problem I suppose.
I did see installation pics where the guy cut PVC pipe to angle the guages. I can't remember if the trim ring was attached to the pipe or actually slid inside the PVC. The PVC was set in a pipe organ form. End result was cool though
OneTon, how about a day/night rear view mirror? Any gray interior trim parts? I really need the 2 short pieces that go from the A Pillar to the Kick Panel. This weekend I'll see what other small parts I need.
