I want to put driftmaster rod holders in my boat. but, i'm having problems finding the ones i'm looking for. I want the troller (pro) with surface mount stainless bases. here's the fun part. I want left hand and right base threads for opposite sides of the boat. does anyone know where i can find these all in the same place?? i've found places that sell just the right hand ones, or dont have the bases i like, or out of stock !! where are you buying them from?
