Review on 🚣 SMARTENPLUS Universal J Bar Kayak Rack Holder - 2 Pairs of Heavy-Duty Kayak Rack Carrier for Canoe, Boat, Surf, Ski - Roof Top Mount for Car, SUV, Crossbar by Robert Hole

Does not fit my 2004 Xterra. The supplied carriage bolts are metric, not standardized. I've searched everywhere for a replacement M8 carriage bolt long enough (@90mm) for my stock roof rack. Lowe's, Home Depot, Ace Hardware do not sell metric carriage bolts. I ended up ordering them from Grainger. I only needed eight and had to buy 50 of these for $13 with $13 shipping. They just arrived today and as the length has been increased the screw head has become larger. It won't fit. This roof rack was a total disappointment and I spent over three hours looking for screws that were a little longer. All the company had to do was add eight longer bolts for those with taller roof bars. Very disappointed!
