I'm happy to hear you like my truck. It's always cool to hear someone say they're inspired to tackle their own project based on something you did.
most of the details are throughout this thread, but the rear bags are RE7's as well, and were simply mounted in place of the factory coil springs. The notch is the standard ECE notch that you'll see a lot of the guys on this forum using. I'm also running some home made 2.25" blocks, but they really aren't needed. You will also need to get an adjustable panhard bar from ECE as well so that your rear end stays in the correct spot.
make sure to take lots of pics and post them up in a build thread when you do start tearing into it.
You could always save some time and just buy my truck. $11k takes it home. I'd have no issues driving it to TX either
