rear wheel cylinders in hq to hz are different to wb for what its worth...spongy is usually not the booster... is it running the hq hj booster with the hq hj pedal as hx hz booster and pedal are different so if you mix a hqj booster with a hxz pedal it does not align and vice versa.

bleeding should be done left rear right rear left front right front..try re bleeding as you will still have air in the system causing spongy brakes.
