There's nothing wrong with it, I just thought it was a carriage bolt that I could replace with a slightly longer one. I put some KYB shocks on from a T3 (with 36" front end from alt impact) because I'm tired of throwing money at those crappy floats. The bushing and mount width on the KYBs is just a hair more. Enough that I can't get a good purchase with the stock stud and nut.
So that's actually a stud with a splined shaft and not a carriage bolt?
alternate question: how do you get the bushings out of a kyb shock?
They don't press out (at least not easily) and look like they're incased in some rubberized stuff to allow the shock to move side to side a little.
