I have a 91 N/A 2+2 Auto.I purchased a 90 N/A 2+2 for parts, but it is a 5-speed and has too many new parts to tear down. (new exhaust, timing belt, clutch, tires, stereo, etc.)So I am parting my 91 instead. Have already removed all my leather out of 91 (90 has cloth and just realized I will be losin two things. My Air Bag SRS and my Auto. climate control.

Can I switch just the control panel, or is there more pieces or sensors, etc. on the 91 that I would have to track down and remove? (for the Climate Control)Thanks!

Swapping CC's is more complicated than that. It's harder than changing the heater core. You basically have to change every aspect of the CC system.
