Bluebird, My current front suspension is completely original. I am going to change from drum to disc brakes in front. At same time I wanted to lower front end so in was thinking of using lowering spindles. As I will have front end apart I thought that I should also replace turbulent coil springs at same time. My passenger side could spring has rubber spring blocks in it. Driver side does not. Not sure why but car sits perfectly level. Thought using coil overs would be easy button to both set ride height and refresh suspension. Ideally new tubular control arms would be nice but car is used just for cruising and tubular control arms are quite expensive and not in budget right now.
