I've been doing some more hunting and found some NOS stuff for the unitized project. I located an NOS ignition module, and NOS distributor cap housing and an NOS coil (which is on the way at the moment).
I also found another remanufactured unitized distributor at an online auto parts store and when I opened the box it turned out to actually be a 1972 1112127 (455 non-HO) with a 1K13 date code. So that is as close as I'm going to get to a 1112133 at the moment. And seeing that I only spent about 1/8 of the cost of a 1112133 for it, I was quite happy.
Here's the instructions with the NOS control module. It even had the little tube of heat-sync grease still in the box.
