Here is a link I posted on here somewhere already, might be "sticky" worthy along with my diagrams?

I just added the "GP" brace to the wagon. Kinda lost my mind for a moment and painted it and the jounce bars, gloss sun yellow.
Kinda like it and when the air dam is put on it is hard to see anyway.
The "J" bars and "GP" were not designed to work together.
I got a 1/2" grade 8 bolt (maybe 2" long) and dropped it in with a thick lock washer.
Mounted the J bars to the cradle by 2 threads with stock bolt and lock washer.
Slid the ends on the 1/2 bolts and put on a grade 8 nylock washer agian by 2 threads.
Now that they were in place I removed one nut, installed one end of the GP brace and reinstalled the nut (just 2 threads again) but with a flat washer this time, repeated on the other side.
I slowly walked the GP brace up a turn at a time working from side to side.
One it hit the jounce bars, the cradle bolts were tightened.
I then hit the nylock with an impact gun, it pulled the ends together real nice.
It did help the car also. I notice it more when braking/turning over bumps, feels more solid and I don't get as much vibration threw the steering wheel.
