Switching to gauge dash????

What is required to swith to gauge dash? New harness under the dash? Anyone know of a nice dash panel that uses after market gauges?

Well here is what it takes to rewire your existing wire to go to the guage type dash:
The following is for a gauge dash this gives the numbered position of the wires in gauge dash and followed by what it supplies, then number from idiot light dash you move wire from.
1-Black with white stripe (alternator) This runs from the 12 R from voltage regulator and should have a inline fuse.
2-Tan (Brake warning light) Original position 2
3-Pink (Fuel Gauge) Original Position 7
4-Tan(Fuel Gauge) Original Position 4
5-Empty(not Used)
6-Dark Green (Temp. Gauge) Original position 5
7-Black(ground)Original Position 6
8-Gray(cluster light feed) Original Position 12
9-Medium Blue (Right turn) Original Position 11
10-Lt. Blue (left turn) Original Position 10
11-Lt. Green (high Beam indicator) Original Position 9
12-Black/w brown stripe use wire ran from the junction block near battery mounted to passenger side fender with a inline fuse located at junction block end.
Remove the wires from your loom plug and place the colors in the # on plug that corresponds with the color from list above. You will need to replace your idiot light temp. gauge for a temp. sending unit with gauges. The black and white wire feeds from the 12gRed wire off back of alternator and requires the use of 2-4amp inline fuses, this wire you need to make and run. The DARK BLUE wire that was originally in #1 position should be deleted because this was the idiot light for the oil pressure.

Wes,
Can you clarify the black w/white. You say to install with 2 4amps fuses? In the one wire? How are the wire connectors released from the dash connector? Is this where the changes are made?

Yes those are the dash connectors...
Here are some pictures, these come from Pauls website.
