Blazers have the brackets welded to the crossmember ours are bolted to the shock mounts.
The red circles are where you need to drill holes (make a template out of cardboard using the bracket) one hole is hard to get to I used a 12" long 3/8 " Bit. The bracket is outlined in red.
It takes about an hour to drill the holes, an hour to install, 2 hrs to paint & detail.
