I guess we have done just about every open rear into an AD that exists but done a Trailblazer into a 50 3100 that was a first. Track width is perfect and has a CLOSE to 6 on 5.5" lug pattern. It's metric so early wheels won't fit but one can drill the old pattern putting the inch holes halfway between the millimeter holes. The disc rotor is also the E-brake drum so the AD E-brake cable is easy to hook up. The one pictured has been drilled 5 on 4.75 to match the rotors on the MII ifs and has 17" wheels to clear the calipers. Tires are 255/85/R17 and look good on an AD. Yes, it has the "potato digger" stance right now but that will be remedied.

Poor picture under bad light but gives an idea of the "look".

Trailblazer track width clears both fender lip and frame rail:

Re-drilled Trailblazer rotor is way bigger than MII fronts so will definitely need a proportioning valve:
