I know this is an old thread, but I just installed mine and I think I screwed it up. Is there supposed to be play in between the top nut and the upper perch? I have the 2 nuts all the way down and there is still a gap until I preload the springs. Did I miss something from the old struts? I have everything installed and actually had to drive it because the shop was closing. I hope I didn't destroy anything. Help!
