how do I mount Frontrunner Gerry can holder to round roof bars?

[rc51kid]

I have. A Gamaviti roof rack ony fj80. I just bought a Front runner duel jerry can holder to mount on the Gamaviti rack. I know I will need to get creative. But how have other people attached the front runner to other round bar racks?

pics would help, but offhand either a U- or J-bolt setup clamping the can bracket to the round rack, or drilling and bolting thru both. The rack piping is not likely to be thick-walled enough for drilling and tapping, so you can bolt the can bracket directly into it. Depends how you want the parts to sit in relation to each other, besides being simply secure.
