Yes that's correct, we all used the 4" bolt rather than the 5" one and found success thanks to JLURD's experience.@JLURD and @toolaide4fit :
which step is this? I’m going to start install this morning and try to get it done this weekend. I think you’re talking about:
VII Final Tire Carrier Installation, Step 9. where it says to use the 5” long bolt.
Is that the right step you’re referencing? I just want to make sure.
