Obs box stop rust

Hey does anyone know where to drill the holes in the inner fender well of the box on an obs so you can wash it out to keep the dirt and salt out. Does anyone have pics of theirs thanks.

Re: Obs box stop rust

A guy on here that bought a rust free bed from me did it to his. pretty sure you drill out all the spot welds along the wheel well lip, then use a cut off wheel to cut out area you want access to. so then you still have the support of the inner fender, but can still get up in there to keep in clean. I will be doing it when i get a new bed. mines too far gone...
