Just for reference, here is the manual telling dealers how to field install the AC unit. You can reverse engineer so to speak to see what all is involved or different.
https://www.packardinfo.com/xoops/html/downloads/55-56ACInstall.pdf While there were some changes in the defroster air flow setup vs non AC cars that you are stuck with, if you do remove the AC & wanted you could fabricate a smaller enclosure out of sheetmetal or perhaps modify an original plenum setup if you have one to accommodate what is now there. With dash out it would be easy to get rid of the huge evaporator box & would make future under dash servicing easier.
AC was such a rare option and if you have the top vents, more the better. How much of the unit is present or would it take to make operational?
