Step bumper fleetside question different styles?!

[silverado_men]

I got a question about the step bumpers on fleetside trucks. I want buy a step bumper for my fall guy truck project but I can’t find the right style. My truck got a step bumper by FEY Company and the edges goes hard round mid of the tail lights (see picture).
The fall guy truck used bumpers the goes smoth round beginning at the end of the tail gate. It looks much nicer and I want the same style. Anybody got an Idee where to get or which company made those fall guy truck step bumpers?!
