John,
All the important bits are there. Starting at the bottom of the picture you first see the rotor and then the edge of the bearing/hub assembly flange, you will need to buy the bearings and rotors, I bought mine (Federal-Mogul) from NAPA for a very reasonable price. I am not positive, but it may very well be that the bearing/hub assembly you have is the same.
Next, you'll see the nearly 1" wide spacer/caliper mount bracket with the caliper mount bolt just started and, obviously the caliper to the right. Now this spacer/caliper mount and short shaft can be purchased through GM (fairly expensive), but I'd check a wrecker, Corvette shop or possibly eBay. Then next thing you see is the upright. Now, where the spacer/caliper mount interfaces with the upright is the only thing you'll have to get fabricated. The spacer has a groove cut around the edge of interior opening which faces the upright. Your upright should have a raised boss that centers and holds the spacer. The boss on your caliper is going to be a lesser diameter than the recess in the adapter. I had a local machine shop make mine and it was less than $30.00 for both spacers. As I recall, they cut two ≈¼" discs from a 4" round billet and then machined out the inside, now these are rough numbers not exact, so you end up with a ≈¼" x ¼" ring of aluminum. You'll need to mic what you have to get exact dimensions.
Now for the two SS connections going to the caliper. The one with the rubber sheath on it is the brake line going to a banjo fitting. (I bought the stuff from Pegasus and fab'ed them up.) The larger one going over the top of the brake line is a Lokar SS parking brake setup. The caliper should come with the hard point which you see (the arm with the round head pointing towards the center of the car) and the actuator arm for the parking brake (just to the right of the rubber cap on the speed-bleeder.) The spring on the cable between the two comes with the Lokar kit.
Edit: I guess I should explain that the parking brake works by mechanically engaging the disc brakes through the cable. Yeah! No damned shoes to fool with!
You may have to buy the 6 (3 per side) bolts that mount the hub/bearing/adapter assembly to the upright, but that will depend on your upright I suppose. Now the only part I am not sure about is the short shaft and the cross for the ½ shafts. You see I planned mine this way from the beginning so I knew what I was going for. If the bearing/hub assembly is the same, I think you are golden. If not, you'll need the short shaft to match it. I am nearly posititive that the universal is the same because I spec'ed my ½ shafts by part nos. based on all C4 stuff (as it just dawned on me) and it worked fine.
