I will post some pictures but I now have a factory tach in my dash and moved the fuel gauge to the lower left corner of the dash. I also rebuilt the the a/c unit under the dash and have the system working by going to proper outlets when it is selected. I also got the rear air unit back together.

I then went to charge the A/C with Freon and couldn't get a vacuum so I pressurized the system with compressed air and found my leak. Someone had cut the high pressure line going to the back of the vehicle. They had cut it with a pair of heavy duty dikes. I don't know why anyone would cut it. But I was able to fix it using a Swagelok 3/8" tubing union and then pulled a vacuum on the system and charged the A/C system with freon. Now I have A/C in the front and back.
