Peter I have been using Williamsons
http://www.williamsons.com/ for a couple of years now, They are a couple of good ol' boys out of Arkansas and do nice work. They could convert that unit for you so it works with modern technology. I just bought a set of NOS brand new in the box Sun Blue line 2 5/8 gauges from them. It is funny cause I just got them today. I got a fuel pressure, oil pressure, ampmeter, and chrome mounting bezel & bracket for $394.00 including shipping! Try and beat that with what these things are going for on e-bay.
