Axle end bolt pattern ?'s
I have a chance to pick up a 3.42 10 bolt out of a 92 Camaro for the Formy, but, it was a disc set up and I have drums. Are the four bolts on the end of the housing spaced the same or am I out of luck? I'm hoping I could remove the caliper brackets and just swap over my drums. TIA

No, they are completely different. The disc thing is a small flange with 4 bolts; the drum one is a tall thin flange with a big hole at the top for the wheel cyl, and a couple of little screw holes for the backing plate.
People say you can modify a drum flange to hold disk brakes. But I fail to see how that's possible, having had rears of the 2 types sitting next to each other.
The 92 disc setup (unlike the 89-back system) will just bolt up to a drum car and work fine. I'd recommend leaving it all alone and just putting it on your car.

No need to change master cyl., prop.valve, or e-brake cables? BTW, it's supposedly off a B4C car. Are those the big discs or the regular ones? And, if it is, will it still work as you say?

Yes those would be the ones with the larger rotors, and the aluminum PBR calipers.
In at least some of the years the PBRs were used, the same MC and PV were used on both drum and disc cars. So it seems safe to assume that the hydraulic requirements of the PBRs are fairly similar to those of droms.
I have a PBR rear on my 83 right now, with the OE MC & PV that came with its drum system. Seems to work just fine.
