    Yeah, I'm a bit bored, saw one yesterday and was kind of wondering exactly what they are using now. (parts for disk swaps maybe, etc)

    Obviously the casting has changed a bit, (flat across the bottom) but knowing GM it's probably still a 7.5 or 8.5" ring gear in there. :)

    You say current style gov loc. Any different than what I see on Eaton's site, or what they've been using all along? (except for the carrier which I'd heard had been "upgraded" at some point)

    Any notes on the brakes? Disks standard, optional, drum in hat, diameter, etc?

    I know the newer Astro's are six lug 13" disk rears (larger than the front!!??) just hoping for something other than the Cadillac setup as a donor. :)

    They look the same style of locking unit when you glance at it . They show the same looking device on AAM's site when you scroll through the dif pics .

    Looking for some stuff online , but can't find swap info .

    Yes, I see a bunch of diff's listed on AAM's sites that if I didn't know better, would think were all their own products. :) Eaton posi's, e-locker, and gov-locks, Auburn's, Zexel Torsens, looks like they use offer all of those in the axle assemblies.
