[Axleman]

...I suppose you could do a body swap with the whole Trailblazer chassis but that was not what I meant. On the AWD Trailblazer SS, the front axle is mounted to the oilpan (not the frame) so there is nothing to fab up to get an axle in there especially if you are planning to already use an LS engine. The only thing that would need to be done is to make some room to get the halfshafts from the axle out to the knuckles and switch the knuckles out for some with a splined ID that would accept the halfshafts. For the knuckles I think you could use GM minivan (Astro/Safari) AWD knuckles.
