Nah using high misalignment spacers you need to get a larger dia heim bore so the HMA can be stepped down from a larger outside dia to the correct bolt size. Also he doesnt need high misalignment joints, and the ones I specd out and use on all my 4 link kits and what not are 20deg 15Klb or 23Klb (.5 or .625 bolts) load rated. You would sheer a bolt before these let go.
and they are mounted horizontally under the car so they have 360 deg travel really.
Are those X-Series rock ends!? all rebuildable goodness and belong on a monstertruck! YESSS
