@86Scotty When it came to adding running boards or steps I fabricated my own from stock steel & aluminum parts along with B7 hardened steel all-thread rod and associated nuts, washers etc. I designed mine to use nothing but existing factory-created through holes, didn't have to hang anything off the body pinch welds nor drill any additional holes. For testing purposes I have a neighbor who weighs close to 400# so there's high confidence mine are quite solid.
I guess I've seen too much damage from poorly installed steps/running boards over the years going all the way back to when "conversion vans" were rampant, being built by shoddy outfits that sold them as quick as they became available, too many shortcuts taken when they cut or drilled into the finished body.
My perspective is aimed towards those who want to keep their vehicles as rust-free as possible--we all know that's never an easy task.
