47-55.1 Rear suspension suggestions

[67ranchhand]

Hello everyone. I’m usually over on the 67-72 side but I’m getting back to work on my 51 3100 5 window. I’ve used the search function for this question but can’t find an answer I’m looking for. What is a good junkyard rear suspension to use on these trucks? Prefer a leaf spring setup. I have a 73 posi camaro rear but I found a zr2 at the junkyard today. I like the rear suspension on it with the sway bars and such but I need to get a tape measure out and do some figuring. Any other suggestions would be great. I was Thinking about a TCI setup so I don’t have to deal with all the salty rusted parts at the yard. Thanks everyone.
