Don't forget your drain hoses too! http://thepartguy.com/images/PartsForSale/ACandHeating/ACBoxes/GMDrainHose_WM.jpg
Finally got mine put back together. Rebuilt POA and recalibrated Expansion valve from Benny. New Evaporator and fan installed. Cleaned up and clear coated. Just need to put insulation wrap on temp sensor on tube and install in car.
Thanks! Bought the evaporator from TPP back in Nov 2015. Been sitting in a box since then. Part number AC1007A. Too funny I paid $10 bucks more than the current price now. Top tube where the POA mounts was too close to bracket. I had to bend my bracket on the suitcase a little bit to get the POA to fit. https://www.thepartsplaceinc.com/pr...conditioning-evaporator-core-gm-3014086/20314
