I installed a Iberia rack IB-RA5 on to my Radrover 6 Plus. The front mounting arms were too short to reach the seat stays. I fabricated new arms using 3/4 x 1/8 flat aluminum bar stock and cut to 13 and 1/8 inches. I drilled holes in the ends for the mounting bolts. I then painted them flat black to match. It's now strong and sturdy.
