    The HD GMT-800's were not available until 2001. All 3500 pickups (and some 2500s) were GMT-400s through 2000.

    It was 1994.

    I'm not sure where you're going here.

    if AAM took over the 14B stuff in 94 as you say....... why do I have an OEM corporate 14B in the back os my 2002 2500 suburban, and can get corprated FF 10.5 14B in trucks up to at least 2010
    the 1150 is AAM since 2001.

    AAM was started as a buyout of part of what had been GM's Saginaw division. It's a spin off company just like Delphi. AAM builds the axles for GM.

    The 11.5" axle has always been AAM, GM never built it. It's kind of a bigger 10.5".

    If you still want to convert your rig to rear discs, then this outfit has been doing it for over 35 years, and has NEW calipers that allow you to keep tour E-brakes;

    Those are Cadillac/Olds FWD rear calipers. TSM even calls them "Small GM Rear". I doubt they would be an upgrade in braking power.... maybe weight?

    You got to dig a little deeper into their website, and their are a couple of mistakes in it.
    The caliper you referenced, the #3110, is the small one with a 2 1/32 piston.
    You can get the larger caliper, #3120, which has a 2 13/32 piston, a big difference in swept area.
    Its just that the website miss-identified it as a front caliper.
    I know, I put one of their kits on an 8,600 gvw square body with a FF 14 bolt, that regularly carried heavy loads, and the stopping ability was much better than the factory disc/drum set-up,,.
    However, I agree, that if someone can get an 800 axle for cheap, and change the mounting scheme, than that is a good way to go.

    Western WA from Eastern WA, aka the wet side from
    Richard, for the 8-lug trucks it is possible to install the knuckles (and bearings, CVs, etc) from a GMT-800 truck, converting the front over to the newer dual piston caliper and/or whatever exists in the aftermarket for the GMT-800 trucks. Post #64 in my thread, hopefully this link works (I have a high post/page setting): https://www.gmt400.com/threads/1996...nv-4500-daily-driver.23693/page-4#post-853821

    Continuing with what you've mentioned it is also 100% necessary to perform an ABS bleed procedure with a bi-directional scan tool to ensure all of the air is removed from the system. I've seen so many threads where someone throws countless parts at a squishy/soft pedal and when they finally take it to someone with the proper scan tool their problems are corrected.
