I managed to get the cable to fit into the bracket, but there's no way I can leave it the way it's routed. Here are some more pictures (because it's fun to take pictures with a digital camera!)...
Original caliper mounting:
I don't have a picture of the original parking brake cable routing, but basically it came out from the torque box area, was zipped-tied to run along the LCA, then went under the axle to the back of the caliper. Pretty simple.
New caliper mounting (opposite side of car):
Here's the new/temporary parking brake cable routing:
The cable isn't long enough to route it under the axle housing and still reach the parking brake mechanism with the caliper now mounted up higher than it used to be. If I try to run the cable between the shock and the brakes, the shock is in the way (the cable ends up running pretty close to the caliper and can't make such a tight bend to turn 90deg into the bracket).
Of course, this is with this corner of the car jacked up, so the suspension is drooping right now. Once the suspension is loaded the cable and spring are going to be fighting to occupy the same space. Not to mention once I get the wheel/tire mounted again the tire might rub the cable at the front of the wheel well.
All in all, not a solution to the problem, but thus far it's the only way I've been able to make the cable even reach the caliper.
