Porterbuilt 4 link, does anyone have pics of 1?

[Rigo's 70 C10]

Does anyone have pics of a Porterbuilt 4 link system? I am thinking about getting a narrowed rear end for my 70 and a Porterbuilt notch in the rear. I think the only way to do that is to run a 4 link system. My truck is on leaf springs right now and its driving me ape S*&t. Everything is geared for the trailing arm set up! Also, is it possible to run 22s all around and lay frame? I guess what i should ask is how tall of a tire can i run in order to lay frame?
