Front
rear
Position the spring so the bottom end (the one that isn't flattened) ends up between the two holes in the spring pocket. Position it in its pocket at the top, which may require raising the jack a bit just to hold it in place, and then get the jack positioned so the A-arm is roughly lined up.
rear
Swap isolators to the new spring, orient it so the flat side is up and the bottom pigtail points to the drivers side (for BOTH springs).
