i think thats just green air line you can get it from gravity worx i think but hey i just wanted an easier to find thread for the millions of people who are gonna ask questions on how to lay a pup out on 22's.
welds look alright ive seen worse (hence the reason i dont have pics of my front setup on my truck)
to me it looks like the gussets are 2 pieces put together and looks like the metal wasnt clean before the weld. on the control arm pic the big tack looks like its just there. maby a cleaner surface would have helped some.
