Karsten, you seen my rack install?? been some time, if so....
anyway, the steel in my brackets is only ~1/8" thick, and main support is only a 1" square tube, cut/welded at an angle to support the rack on the left side, and same gig on the right side...simple clean easy install, took a 1" wide 1/8 thick steel bar from bottom of left bracket, and it goes to the forward/outer where the old power assist bracket was tied in on bottom of frame, been that way for years, solid as hell...even with the addition of the cross support between the A arms....Given my experience, I fail to see the need for 1/4" steel WAY over engineered heavy mounting brackets....especially when lousy welded....:harhar:......
