Well, the battery is all hooked up now and the car is finally running again. All that's left is to secure the cable to the bottom of the car with the little plastic loops that came with the kit. Not quite sure how I'm going to do that, though...
I would have installed the new lower control arms as well, but I can't get the rubber bushings out of them in order to replace them with poly. They don't have the lips that the poly bushings have, so there's nothing I can grab onto and pull. Trying to push them out didn't work, either. Grrrr!
I'm so close...
