I ended up doing the floor holes as well on my first rear shock change, so much easier. Not sure if you found some caps/grommets or whatever but I just used some flex seal tape over the holes, infomercials aside that s*** is super sticky and haven't had any dust coming through.
!! My first thought was I must have either not fully pushed in one of the gazillion connections or have some how bricked something else. I was literally excreting rectangular hard formed objects!!


That soft aluminum turns to squares if you do it right. Hopefully, this last $160 will set you on a path to victory.
