Started with a 3x6 3/16 tube @ 55"
Im sorry i didnt get pics of each step, i get a little involved
I cut 1/2 inch out of each of the shorter sides of the tube so i was left with 2 peices of channel with dimensions of 2x6x1/2 inches. I then cut the ends to angles on all 4 ends.
I then plated in the still straight part of the channel with 3/16 x 6 flatbar.
made cardboard templates for the other two peices on each end, cut em out, welded em up, and ground them smooth, they are sliders.
Unfortunatly this is where the fab pictures stop, i got into building and forgot to take pics.
But, on the top of each slider i welded a 1.5x2 inch tube to fit into the channel under the rocker panel, then jacked it into place and welded the frame legs onto the slider and to the 1/4 in plates bolted to the frame.
They are very solid, my fatass jumping on them they dont flex down.
Heres how they look on the truck, i still need to remove them again and paint them and weld some raised expanded on top.
