I like the rack from Calmini and Rhino, I like the way yours looks. ÂÂ
I have an idea of using an Olympic Maxi light bar made for a jeep (available from Quadratec etc) and having the main U bar re-bent and or cut by a shop to fit the taller but narrower windshield.  I will bet that the mounting tabs will fit on the frame around the windshield in about the same manner as on a jeep.  I was thinking of one for the front above the windshield  and one for the middle above the rollbar, and I would have my rack and still be able to use the fold back option for the top.  I am trying to make this in a way that will balance my surfboards over the middle of the Truck, and still let me use all of my top options.
Thanks for the replies
