So who out here is running a yfz rear. I have one that was modded for a blaster and revalved by gtthunder. The top bolt has been turned down and has spacer so it goes through perfect but now has play. I'm curious if this shock needs some play at top and if so how much and if anyone knows whether the size is same as say 400,450,ltz, as in would oconnor bushings work to take up play?
