Saw a fabricated diff cover in the clearance section at Summit, and almost grabbed it. Debating asking a teammate to snag it when they are up that way later this week. Looks like it was made to put a triangulated 4 link in a 73-87 Chevy truck, but I could probably cut the brackets off, re-weld one in the center, and use it for a three link. Probably not worth the effort, though. Stopped up and got to hang out with Patrick for a little bit, and picked up some parts that will likely go on the challenge car when the build phase actually begins.
On a positive note, despite FBM being a hive of scum and villainy, I made $45 in sales off the Trailblazer. They showed up for the bumper cover, and ended up also buying a few interior trim pieces.
