VinAir in a 61 Pt 5

I wanted to use the long inside vents but the ducting at eh center was just to tight with the defroster duct at the same place so I had to use the singles. I also too the opportunity to add new gauges as I wanted to add volt meter as I was putting in a alternator instead of the old generator.

Probably should have mentioned that I also sourced original crank and water pump pulleys intended for A/C. They are different diameters and backspacing than the non A/C pulleys. Part of this change also requires different hard to find PS pulley. It is supposed to be larger diameter and also the groove placed 3/16 closer to the PS mount to get it to align up properly with the crank and WP. I had to source one that is a spun steel pulley and not the factory correct cast iron pulley. It is slightly too large a diameter which only under drives the PS.
