I again used the (free) loaner spring compressor from autozone. It works great. Insert the rod down through the upper shock mount hole, and attach the threaded hook(it comes with 2, remove the one without threads. Attach the longer of the arms on the hook to the outside of the spring and the shorter to the inside. It compresses the spring easily and at the correct angle to attach the lower "A" arm perfectly.(This tool is worth using even if it wasn't free)
