Should have the dash reinstalled this weekend with the new AC Evaporator Core & Heater Core. So now I'm looking for a list of part numbers for everything under the hood.

Note: I have removed the rear AC and will either need to block off or replace the AC lines with the 3 way blocks in them.

Anybody that can help me with this list?

Thanks in advance!

Managed to use the internal gears from the rear AC blend door motors to rebuild the front blend door motors.
Replace AC EVAP core and heater core and cab filters. Putting dash back together tomorrow.
Next I guess it's off to the junkyard for hoses from trucks with no rear AC since I removed mine. Ordered o-ring set on Amazon for assembling all that.
Not sure if I need to replace other ac components other than my bad compressor or if they can be re-used. Could really use advice on that if anybody has any.
Thanks in advance.

I tried to help and look up some of those parts but there is a GOB of choices at RA. You can even get kits with or without the condenser. I would do it all since everything else is new.

Compressor, orifice, hoses, condenser, flush reused hard lines and clean in front where the air flows to the condenser.

Thanks but you didn't have to do all that.i was hoping someone already has a list. Thanks a ton though, really appreciate the effort.

I salvaged some ac lines that look to be fairly new from an Avalanche at the junkyard.
Got a compressor, condensor, orifice and accumulator on order. Got a pressure switch. Not sure what else I need to be honest. I'll find out once I've got all this out together.

I've still got a free hours left putting the dash back in after the EVAP core and heater core replacement.

Oem EVAP core.
Oem condensor,but downgraded to condensor for vehicle with no rear ac, so it's a little smaller but still a direct fit.
Oem accumulator.
Oem hi and low pressure switches.
Ac line from accumulator to condensor, ac line from condenser to compressor and ac line from compressor back to accumulator all taken from 01 Avalanche. (Cleaned and all o rings and valves replaced).
Now just waiting for my motor guy to do his work,then we replace the compressor and charge it up.
Oh, also replaced all blend door motors while replacing heater core and EVAP core.

Thanks to everyone who contributed info, especially you google.
