[OG68]

I loosely connected the end links first and then raised the bar to the frame.
Ideally you want the ends to be parallel to the ground so you may have to cut the end link bolt/spacer to make it fit correctly. I used a kit from Summit with different thickness poly bushings to keep the end links vertical and the bar parallel to the ground
I put the front tires on blocks to keep the springs compressed which shortened the distance between the lower control arm and bar and to allow working room. Installing the end link bolt with the bolt head at the top helps somewhat.
