What we did was got the shape that we wanted our hinge to be then we cut them out with our band saw. To get the holes you see in them we don't have a cnc mill so we just made them out of three pieces and welded them together. The center of the hinge is made out of 1/4 in plate and the two on the outside are made out of 1/8 plate. We drilled the holes in the 1/8 plate and then welded all of them together. If you don't want the circles in there all you would have to do it make one out of 1/2 in plate. As far as the struts go The rate of the shocks are 300 per side. We got them from LST in Saskatoon, SK. The Part number for the shock is c19-14-1350n. He can put any style end on them as well.
