Hi Mark. I sure don't mean to discourage anyone from tackling a project. It's just a bit of a handful to do an A/C conversion and that's probably what I was referring to in a previous post.
Sure, it can be done, and maybe it's even fun but it approaches the 'next level' in hands on changes. There are so many little things to attend to. If you have a good donor car it really helps.
Whether you are going down the wrong road is up to your abilities, but if you are comfy changing out the dash, you are halfway there. Air is nice and your wagon would be a fine cruiser with the addition.

(hopefully you already have tinted glass?)

It's not to be taken lightly though; bigger rad, fan shroud, brackets, kick panels, pulleys, hoses, clips, wires, cables, relays etc and even the R12 itself.
Make a list and be sure you have everything you need in advance.

ps, some things like the receiver/dryer will be toast if the system was opened up for any length of time. POA valve, sensors etc are also a bit of a leap of faith unless you can see the system in operation.

Well, for my year (67) the vents are disabled. The a/c equipment uses this spot (passengers side) so the vents don't actually work - on either side.

A factory assembly manual is a must. Sounds like you are all set.
