Whats the story with this Aftermarket A/C unit??

One very similar to that (if someone "said" it I might even remember the brand) was installed in my V code 70RR. Frankly I would MUCH rather have one of those instead of factory. Much easier to deal with, if you need to work on it, just dump the charge and pull it out of there.

In fact, until I found "most of" a Vintage Air system on CL for a 'eck of a good price, I was planning on buying a 200.00 evap off ebay, and rig up the rest of the underhood "stuff."

Sears of course never "built" anything. That system could very well BE the same brand as I had. On mine, there was a very heavy cast iron pulley which bolted onto the "stack" with 3 bolts.
