Quoting charlie_pank: Steve, not sure if I'm misunderstanding, but I've currently got the DD tube out of the car and the shocks + springs are just hanging there. When I've finished all the other messing about, I'll slide the DD tube back in, bolt the shocks to it, attach the radius arms and A-frame and put the wheels back on. Is there something I'm missing about having to compress the springs?
That's what I did a few years ago - maybe physically changing the shocks makes it different, or some of them have longer springs, or something...
