6'1" 32" waist. Ran out of adjusting room to tighten the left lap belt side so the cam lock is off center like others have mentioned. It's snug but would prefer it a tad tighter. That little black plastic piece covering the drivers side torx bolt was a PITA to remove. There's a flat plastic clip in the middle along the bottom... If you can get to it vertically through the slot in the top, push the flat plastic clip downward to disengage it and negotiate the posterior segment free...that's it.
