No you don't. Slots are long enough if you push the caster bushing all the way in you can drop the bolt straight down. You should always have the nut on the bottom. That way, if it manages to loosen up, the bolt won't fall out.
You're right I forgot my k member came welded so the bolts wouldn't slide in the slot. Mine hits the body because it is welded maxed. Thanks for the help!
