Heyo!
If you haven't heard of BillieBars, we're an American made company, that specializes in tonneau cover compatible crossbars, and accessories - perfect if you're looking for a low profile mounting option for RTT's, bikes, cargo boxes and baskets, and now...
KAYAKS! We just recently came...
We will try to grab a pic here in the next few days! The soft roll up cover barely kisses the welded supports, we haven't had any issues so far with either the cover or the brackets!
Feel free to shoot us an email and we may be able to help. If you use the unistrut nut (zinc coated one in the pic) you could just get some longer bolts. BUTTTTT - we just finished up some new designed t-nuts that should solve your problem. Shoot us an email - we would love to get these to you...
We have had a lot of people running the Yakima Warrior basket (perfectly clamps around our bars), and have found that using Ski/Snowboard mounts are the best for clamping fishing rods in!
