I appreciate everyone's help on this issue. I've been away for a while so I haven't had time to update. The issue was a small leak in the rear left line that had eventually plugged itself with dirt. This left an inordinate amount of air in the lines. After searching I found the Eldorado has the strangest bleeding order (rear right, front left, rear left, front right.) After bleeding for a few hours. I'd pretty much given up. I slapped everything together and the brakes worked great.
Again, thanks everyone.
