I wanted to see how the +73 B-body LCA compared to a Abody. So to the best of my ability I measured(Calipers)and modeled each LCA in SolidWorks.

At first if you just look at the arms as the B-Body looks a good 1/2" longer. But its a bit deceiving as the differing Ball joint attachment points throws things off. That's why I went ahead and modeled each one separately.

So from this assembly model the two arms aren't too far off in actual length. Less than .25" for sure.
