I have a standard interior 68, with the Muncie 4 speed. The gauge console has a Stewart Warner speedo 160 mph and the other side is a mechanical tach. There is no fuel gauge or clock or anything other than idiot lights.

What should this have in it? I want to add regular mechanical gauges but don't want to mess it up.

The "standard dash" for 68 included a 120 mph speedo on the left, fuel guage on the right, and idiot lights for oil, temp, gen & brake, plus turn indicators.

The "optional" guage package used the same speedo on the left, with idiot lights for brake and low fuel, a"TicToc tach" (clock in the middle and tach around the outside) on the right, and 4 rectangular guages in the front of the consolde, for fuel, water temp, oil pressure and Amps.

Unless you want to spend a BUNCH of $$$ doing the "factory" guage package with repro parts (would cost near $2000 to do it right) I would suggest you troll around Auto Meter's website. They sell a panel that fits into the front of the console and holds 4 round 2" guages.
