Hi Volks,
     Here are some pictures of my dash console / cup holder.

    makes a nice cup holder and install some gauges with out chopping up the
dash. The oil pressure gauge is an electrical type and will show oil or fuel
pressure with the flip of a switch. There are 2 senders in the engine
compartment one for oil one for fuel.  The coolant pressure gauge displays
the amount of coolant pressure and gets it's input at the vent plug on top
of the radiator.
