whole installation and go find that longer bolt, but I was genuinely amazed when that factory bolt went right in. I can only guess why it did: I had that entire section settled in snug while I left the passenger side completely loose and I got the rear bolt barely threaded just a turn or two and then started the forward bolt and it just threaded right in, then went back and forth with tightening to even it all out. I have no idea if any of that had anything to do with it working out, but WHEW!!!
