I know that before i remove my AC i need to have the system depressurized/evacuated. In order to fully remove the system, what components do i need to take out. I already know that i must remove both the condenser and compressor and install a new AC delete pulley, but what else must be removed. Any tips would be appreciated.

also, all the wires in my car are wrapped with a plastic tubing, but it is getting old and starting to crack and break, and the wiring are starting to be exposed. What is a good product that i can use to re-do this job.
THANKS for the help, this will make the installation of my header a lot easier plus i have never used to AC once and i have had the car for 2 years.

When I removed the AC from my old 84, I also removed the accumulator (easy), the blower motor and the entire housing for it (not too easy, but not bad either). Then you have to fabricate a cover plate to block off the exposed hole in the firewall. I just riveted on a sheet of 16 gauge steel and sealed it with RTV since it was supposed to be a strip-only car and not be pretty at all.
Then I removed all the ducting inside including the heater box and core, and HVAC controls, tubing, servos, and cables.
Man did that make the engine compartment look empty! And under the dash as well.

You can buy convoluted tubing at an auto parts store in 6 or 8 foot rolls for $3 a roll. It doesn't have quite the same quality feel as the GM stuff, but it does the job.
