Should have painted some color. All made from .750” crs.
Two ea. 2” long, drill and tap .5x20” threads to tap depth.
One each 7” long to fit your shocks. Drill and tap 9/16” to fit your shocks, drill and tap other end .5x20” to tap depth, bend 9/16 end to match shock angle.
Drill .5” holes in frame in locations to accept shock loads.
Mount three studs just produced in appropriate mounting locations to fit shocks, make patterns to fit between three mounts and copy out of steel, weld two samples to studs just produced. Disassemble and finish welding, paint and reassemble, mount shocks.

Hope this is clear, works really well, cheap to make.
