Stake side pockets for Ram?
 

Hello,
I have a 2001 Dodge Ram 1500 with the original bed. I'm looking to buy or make some inserts for the bed rail pockets. I want to built wooden stake body sides for the truck, but need something to transition between the original metal bed pocket and the wooden sides. Any ideas?
I saw something in a website that I could weld on. It was simply a three sided piece of bent metal, like channel iron but thinner. I need something like that, but with a transition to the bed pocket.
Thanks,
Steve
