Adding AC to a 88 custom
I have an 88 Bronco that I want to add AC to.
Things I know I will need:
AC Condensor
AC/Heater Blower motor
AC Compressor + bracket + belt
Interior switch / control panel.
Hoses (not sure how many) hard and flexible
What else and since I will be taking most parts from a JY, what should I avoid getting from there?
Thanks, this is going to go slow .

What ENGINE does the truck have? Add it & the truck's other details (year, trans, trim, options, mods, miles, etc.) to a signature so you don't have to remember next time. If you don't know them all, read this caption & follow the links in it:
Read this caption & the NEXT:
Your engine bracket will probably accept the compressor.
You can use an '87-early '88 control panel & inside box, OR a late '88-91 panel & box. I prefer the older because it allows more control over the settings. Get the A/C wiring & vacuum harnesses to match the control panel.
If you get a newer outside box, inspect the vacuum reservoir glued to the evaporator cover - they're known to leak, warp, & even crack the cover. If it shows any damage, you'll need another reservoir, but ANY vacuum reservoir (from ANY vehicle) that size or larger will work.
Try to get a '94-96 (or '97 >8500GVWR) refrigerant system still charged with R-134a, and bolt the compressor onto your truck first, with the JY belt. Hotwire the clutch to see if it makes bad noises, and make sure the condenser gets REALLY hot, and the evaporator gets cold. Don't run it for more than 45sec @ 1500RPM or you could overpressurize it & blow refrigerant out the safety valve.
Don't forget to collect ALL the fasteners, especially those for the condenser.

That's exceptionally rare. Can you downshift from 2 to 1 while the truck is rolling? Does the trans have an Aluminum or cast iron top cover?The ventilation box inside the cab, vs. the one outside, under the hood. The outside box contains the recirc door, blower, resistor, evaporator, & vacuum reservoir; the inside box contains the heater core & all the other doors. Note the "COWL PANEL" (aka firewall) dividing line in this diagram:

Did you get rid of it?

No I can't down shift into 1st. Not sure about the top cover as I have not pulled the carpet because the PO had it glued down. I don't remember the door code, but I did look it up when I first got the truck a couple years ago and it indicated a T18.
