Rod Holders installation help!!

[Bosts1]

Hey guys, I want flush mount rod holders on my gunnels that angle back and out from the boat a little. the back ones go straight back, middle ones little farther out and front ones all the way out. However it seems the gunnel is to narrow there to put them angled. do you guys have these and if so how have you done it. this is the best set up for outriggers. Any input is appreciated. Thanks
