Thanks, I made them out of 1/4"plate and bent them to the 2 widths needed and then welded 1/4" angle in between. As for the mounts it is all 1/4" plate, I used these parts from Ballistic Fab;
Part Number BRK-1048-1 Part Number BUS-664-41
Once welded up I took an unused 3/16" plate truss and cut it down and welded the 1/4" flat plate and welded the above kit to it then bolted it all forward of the stock mount location. It is also adjustable up and down for height changes.
Here are more pics of it to get a clear idea;
Creeper style joint and mount

Cut axle truss and then tacked to back mounting plate
