This is the exact setup I was looking for... so I can fit 66" bars onto the oem rails... Can you show what you had to trim? We'd greatly appreciate it! Thanks!I used the yakima lowrider max kit with clamps for a nissan xterra with factory rack (designed for round factory bars) and had to grind the clamps a little. I can post specifics tomorrow and maybe a better picture focusing on the crossbars and mounting system. Very strong and haul up to a 30' ext. ladders or a yakima skybox 16 for xtra luggage.
