I took these pictures of a beautifully restored Shelby on display in Birmingham because I'm planning to simulate the Shelby interior (sans the Shelby emblems) in my Mach 1. I already have a Shelby style roll bar with the correct boots, and my console has the Shelby/Cougar style lid. I'm planning to add a 140mph speedo, the reproduction Shelby console insert, and the correct wiring for the gauges in the console now that they're available in reproduction. I took some close up pics of a Shelby interior and under the hood to use as a reference when putting everything together.
This is a picture of the lower dash jewels that came on all Shelby's and a few highly optioned Mach 1s. The top indicator says "BELTS" and the lower indicator says "PARK" The bottom jewel is the same one that came in the deluxe console of the 67-68 cars. The upper jewel said "SEATS" in the 67-68 cars and was changed to "BELTS" for the 69-70 cars. The knob on the right is to control the fade on the rear speakers. It was a dealer option on regular Mustangs, but since the Shelbys came with 4 speakers, it was standard on the Shelby. Notice the choke knob at the bottom of the dash. This was a 1 of 1 Boss 302 in a Shelby.
This picture shows how the ammeter wiring and oil pressure sending unit wiring routed into the firewall, just below the rubber plug in the cowl. The oil sending unit wire comes from a short in line jumper that plugs in to the engine gauge feed harness.
Here you can see where the ammeter gauge connects to the alternator output. Although I am using a voltmeter instead of an ammeter, I want to use the heavy gauge wiring connected directly to the alternator output so I don't read the voltage drop of turning anything on inside. Using an under dash 22 gauge source for power detects the voltage drop on anything I turn on such as lights or the blower fan.
