Wait until the springs are installed before ordering the shocks. At that point you can get an accurate measurements for extended length (tires off ground) and at ride height. Compressed height is a bit more difficult to pinpoint. If you call back QA1 with exact measurements they will be able to better accomodate. They may move you over to a different shock model. They ship shocks in a coupla days so there's no need to get them now.
