You've got some very knowledgable elec gurus giving you advice. Only thing I can add is i would get your boards refurbished if at all possible. I had these ones done and very happy. Not installed yet tho...:rolleyes:
We went with a triple gauge set that mounted directly below AC diffuser as well as orig gauges left in dash for 67 Barracuda. Work and look perfect, dont look out of place at all.
