I did not take a lot of pics when I was working on it. I will see if I can find the post that I looked at to do mine.
Here is a couple of more pics.

I just used 3"x6"x3/16" tube. I bought the tube 6 feet long and then cut down to what I needed. Then had some 1/8" dimond plate bent to fit over the bottom of the door opening.

 

Ok this is where I found the information to do my rockers.
I did use 3"x6"x3/16" wall tube.

This is for people who have deystroyed thier rockers, have rotted out rockers, want rockers that will handle some abuse, want to ditch thier lower clearance rocker guards,etc.....

Install time: factor in 3 hours for the first side at a leisurely pace, and the next side about cut that in half because you know exactly what you are doing

whadaya need!?
Some box tubing, i have seen people use 2x4 for it, but i prefer 2x6 for the door protection. 1/8" might be sufficient, but i would reccomend 3/16" or 1/4" if you really abuse your junk. you will need 57 1/4" per side.

tools for cutting/ grinding metal, sawzall, angle grinder and whatnot

measuring tape

welder. a simple 110 mig would do just fine

paint fo bling

SAFETY STUFF, goggles and gloves, welding mask.

a few strong men, or a jack capable of positioning the tube in place while you weld it on.





admire the old busted junk



cut that old junk out via cut off wheels or sawzall blades or both. i cut to the flat spot on the top of the old rocker and on the bottom left about 1/2" of the old rocker sheet metal coming off the floor.

this pic is untrimmed



trimmed and all neatened up.


cap the ends so junk dont get inside them, could also use them as airtanks now.


here is the shop *****, bungee cord controls the speed, and it still fluctuates at times, but when it runs mint she will lay a sick nasty bead.



mocked her up

she looks pretty in there. i ended up using 57 1/4" of 2x6 on each side, fits perfect in place of the stock rocker.


began welding. basically just weld it wherever metal touches. i did a couple inches per time and clamped it together with a c clamp to pull it tight in places.


BAM!




for most wheeling that will do just fine, but if you constantly bounce off boulders and whatnot it isnt a bad idea to tie it into the framerails

Sorry this is way off topic but I figured since there is rust involved in this thread I could chime in, how fast will rust spread through the floor of and xj? I just grinded down a lot in mine but Im not sure if I got it all and dont want my floor to fall out in a year! again sorry for it being off topic guys.

 

do you have a budget? the best thing is to patch your factory holes in the unibody and hurculine it. probably 6 months to a year

 

i did the same thing to my rocker panels. when i got my xj the was no passenger rocker and half of the driver side. i used c chanel and tied it in to my unibody. i wish i would have taken pictures of the install.
