In regards to rear shock angles, check this link

Here is the data for the longer track arm that a just modeled this morning for ya'll. The longer bar helps, but not significantly. I am betting thats why GM never used them on these trucks.
I haven't been a big fan of these long bars simply because they aren't really needed on a street driven truck. Think about it. A stock 3/4 ton truck with stink-bug high rear end height, now fully load it down. Your street driven truck will never see more suspension travel than that, right?
Now if your running a rock crawling 4x4 with a lot of suspension travel like my buddy Tony's Bronco in the last photo below, the long track arm will make a whole lot of sense.
Image below is the frame is at ride height.
Again, note angle of track bar in the following photos
Image below is fully bottomed out; frame is on the top of the rear axle tubes. (NOTE: This moves the axle to the right approx. 1/2" from the std. ride height position)
Image below is fully articulated, hanging left side, bottomed out on right side. (Note: This moves the axle to the right a negligible amount about 1/8")

Here is a photo of an application of where a really long track bar yields the most benefit.... lots of articulation here:
