***Update: 8-14-09: The general consensus is to not make this fitting in three pieces. It should either be bent out of a flat sheet of 4130 or milled out of a solid piece of steel.***
Unable to purchase the .875" x 1.25" x .o95 retangular tubing... I made these up out of .100 4130 flat stock. They still need the 5/16" holes drilled into the up-rights.
