Modern electronics = Full rewire
Oh yeah. Some other goals:
Figure out how to replace the instrument lamps with LEDs.
Replace the amp meter with a volt meter.
Go ahead and remove and repair/repaint the dash....I mean everything is out of it at this point.
Fix the hack job they did on the radio area of the dash and replace the bezel, also cut up to fit the new radio, probably going to need to find a replacement. Put a period look alike with bluetooth in it.
