mounting tracks

[nasc620]

I have a 20 foot aluminum boat with the top of the gunnels is 3 inches wide. I'm thinking about mounting some mounting tracks on top of them but all the ones i can find are 3 1/2 inches wide. Does anybody know what the spacing is for he mounting holes on the tracks is? I've tired to find the specks for that but haven't. I'm currently looking at the traxstech or the ones from Bert’s Custom Tackle. I would just use side clamps and mount the rod holers to them but haven't found any that are wide enough to fit over the gunnels. Thanks for the help

The Traxstech is 1 1/2 inches between the mounting holes.
