I would like to fab up some flat flares to match my front ones, and for the rear, I would like to make it a 2 piece flare. One part on the rear quarter panel, the other part on the door. I would like to trim the fender completely flush with the door, or at least really close. Any tips on how to go about doing this? Just looking for some insight, ideas, advice, before I pull the trigger!

Thanks!
