Much appreciated! I'd be happy to go take some measurements, but my truck is getting a bunch of work done to it and thus, I don't have it right now. So I can take some measurements when I get it back, but I definitely recomment you call TrailGear and not only get the measurements you're after directly from the source, you also might think about whether or not you need to get their inner Cs, their knuckles, and their unit hubs (in other words, how much of their product will work with your junkyard/stock setup?).
If you or anyone else wants to see the build my truck is undergoing (started as just a cage and boatsides but evolved into a complete backhalf and rear 4 link), here's a link to the first of three videos he's posted so far (he's probably got 3-4 more he'll post). He's had the truck for 2 weeks as of yesterday. His name is Loren Krey of Kreyzfab in Pueblo.
