Greg,
Can you post some photos of that sway bar and its mounting? I haven't see the blazer setup, only the 2wd.
Here's all it is...
The u-bolt top plates have a large bolt to hold the sway bar.
The only thing that's even remotely hard is creating the pivots for the center of the bar. A small "box" structure under each of those clamps welded to the front crossmember is all it takes.
