Saltracer's got some good ideas. If you pick a 4 piston brake caliper that bolts on with 2 bolts, making caliper brackets shouldn't be too hard. Depending on what sort of hardware attached to the original spindle, you may be able to drill out old dust shield bolt holes bigger and use them to attach the caliper bracket, or just get someone to mill a flat spot on it and drill it.

If you're willing to do a spindle swap, I would hazard a guess that the late B-body spindle might be a good match for your car, with 12" brakes and a 5x5 pattern. You could probably re-use your lower control arm, and mock it up at ride height to determine the length and offset necessary for the upper control arm.

Stock Car Products and UB Machine offer inexpensive tubular arms in a variety of lengths and offsets. I'm not sure what the cross-shaft bolt spacing is on your car. You may have to get the spindle reamed, depending on the ball joint used. Most stock car shops can do this inexpensively.
