Here are a couple of pictures of the RAM mount balls in place. Pretty useful (nice tiedown point for the paddles during transport).
Turns out with the fairleads on the kayak, you only need one of the 1/4" pulleys. I used a heavy duty carabiner for the accessory interface (where I'll lock in an anchor line, stake pole or drift chute). I placed the trolley on the starboard side since this side of the kayak is stored up when I have it in the garage (this will prevent the carabiner or the pulley from getting damaged or scraping the side of the kayak). If I haven't already said it - modifying kayaks is really cool -
