i made mine,easy to do, used 3/4 steel gas tube, free from work .weld a 12mm nut on the end. . cheap male rose joint about £14.00 from local bearing place, used a 12mm bolt to bolt to axle. flat plate to make bracket to weld to axle. inner track control arm bush for chassis end. i think about 2"box section welded from chassis rail with a cut out for the bar to go in.then braced it all up to under side of floor pan, copy it from a pic and make in position. sounds tight ,but i am also need 2 spacers to go either side of rose joint to allow it to twist. didnt go through floor.
