I've been hitting junkyards now for over 20 years. Many in different states, even countries, and have never seen an LSD up front. If you go on the Dana expert site they list them up to 78/79 in certain models, but pretty sure not one was a GM. I think GM phased them out after the new models in 73, but vaguely remember seeing some in the expert. I'm gonna put one in my crew if if I ever SAS it, we'll see how it does.....
