So I want to post up and get some feedback on my bumper plans...
I wanted to do something rather simple.... so I figured a good starting point is some C-channel. I put together this quick Google Sketch... its not to spec, was just done to be a 3D guide and reference point.
I started the project with 3/8" angle for mounting legs. I planned on running them through the channel so I can use them as shackle mounts. I will beef up the inside as well as add some flat stock outside to widen the mounts enough for 3/4 shackles.
Then my neighbor came through with a 10' section of 8" C. Starting with the whole piece centered to the vehicle. Cut through for the legs. Going to cut off either side right where I will make the first bend, just outside of the legs to follow the TB's lines closely. Will then notch the top and bottom of the C so I can weld the pieces on an angle. I will also cut the bottom lip of the channel off and will notch each piece to taper up 3". This will allow me to raise the sides 3" to fill in the gaps at the quarter panels. I plan on using flat stock to fill in gap under the taillights.
I've since picked up the hardware for the legs, (4) 9/16" Grade 8 bolts per leg, utilizing the 3 factory holes per leg plus a 4th on the bottom, like JD did. Also picked up a 2" receiver and cut the channel for that as well. The receiver sits inline with the bottom of the angle legs and will be reinforced internally with more angle and flat stock, connecting it to the legs to disperse the load.
Things might be a little slow as I do not have a welder and am currently relying on my neighbor and my brother in law to do all my welding. They both lead busy lives and work many hours... so finding common time while its not 100+ degrees out is tricky.
