Fonman, I've just gone through somewhat the same dash crap as you-
original problem was a broken speedo cable, but the job devolved into
my being forced into finding, then assembling the best parts that I
could come up with from 4 spare dash pods, all of which suffered from
varying degrees of dinged/cracked/broken plastic and/or
folded/broken/missing contacts where the console attaches to the
wiring harness.

   The plastic on my original '89 unit is in such awful condition that
even the tab the connector slides onto broke when I attempted to test
it and one of the two studs that the tach face screws into had
dissolved into small pieces.  The speedo was pretty much being kept
from falling to the floor by its cable.

   I knot that it's whistling in the dark, but does anyone here have a
MakerBot big enough to tackle the job and a naked console in good
enough shape to make a decent copy? <EG>
