Heres what I did. Scotty flush mount rod holders on an 82 model. These (black rectangles on the gunwales) are the receptacle for the removable holder that fits in to them. No pic of it together and the boats is put up for winter or I'd take one for you..
Gives a clean look when not used. The holder can be set in multiple positions hor. or vert. Seem strong - at least good for where I'm at. Come in white, grey, or black. and just fit that ridge perfect. Check Cabelas for a picture (they have the same thing under their brand)
