Convert from hub rotor assembly to separate parts?

Yeah, I think I'm just going to have to suck it up and tear my setup down to the spindle to get a better idea of what is going on. I technically have the two piece rotor setup, but I'm not sure that really says much about my car. It was such a mismash of parts when I bought it I think they just kept bolting stuff on until it looked enough like a car to sell it. From the brake hoses it seems like E body calipers, but the rear end and the engine and transmission that were in it when I bought it were more like F body units, so you would have thought the front brakes were too. However, when I bought the hoses to try to flip the calipers front to back, that's when I found out stuff was weird. I've been told I have a C body radiator in it as well, so all bets are off when it comes to guessing parts, lol. I also found out the rear brake shoes are not quite what I expected either as the slot/hole for the parking brake tab was different.

I got to thinking about it some more and got some measurements from the B body forum for some Wilwood drum brake hubs, so I have an idea what the drum brake offset is. I think I'm going to take my hub/rotor off and measure the offset to the hub flange as well and see how it compares to the drum hubs. Maybe they aren't as far off as I think they are. Since I already have the spacers on the wheels I can probably make my existing hubs work, assuming that I can space any caliper bracket accordingly. I just don't want to get things too far away from where they started as that starts putting some goofy loads into things. Honestly, the way things are set up now my brakes are pretty much entirely outside of the barrel of my wheels. Maybe that was typical of the day and age and offered better cooling or something, but they just seem really far inboard with the design.
