I just did 2x6 replacement. The best way to do it is with 3/16" or 1/8" box. I went with 1/4" and even being a certified welder, I had a hell of a time welding 1/4" to rusty sheet metal. Put a strip of 1x1/4" along the top of the rocker after you cut it out. You can use that as a bridge to join the box tubing to the rocker. Drill the 1x1/4" for plug welds and weld the whole way down the length of the 2x6. Knock the pinch seam over and do the same for that. If you have the same issue I did (most of the pinch seam is gone) it will leave a gap between the 2x6 and the floor pan. I used a strip of 4x1/8" to cover the gap and add support. I ran out of gas in my welder before I could put the support legs on, but I'm using sections of 2x3 3/16" that are notched and welded to the 2x6 and welded to my frame stiffeners. Should have the stiffeners and legs on soon! If you need pics, just let me know.

Pictures would be awesome as Im more of a visual person not sure what shape everything is in behind the rockers but they are starting to rust so I figured why not fix it now regret it never lol. I noticed to day I also have a rust hole big enough to stick the tip of my key in in the roof :/ guess Ill weld that up as well. Do I need to sand anything first?
I was a little worried about doing this, but once you get the old rocker cut out it all makes sense. There is a bolt on the side of the floor pan for the seat belt. Some people notch the tubing out for that, but due to time constraints I did not. Make sure you angle the 2x6 down slightly so water will run off and not pool on the tubing.

After you cut the rocker out, take a die grinder with a grinding/sanding disc (i prefer 36g) and clean ALL of the steel. Get all of the dust and debris out of the inner rocker. I used a primer for rusty metal and did 3 coats. Then did 3 coats of spray on bed liner. Don't be afraid to be liberal with it, you're sealing it forever. If you have any holes inside the rocker, clean them up and tack weld sheet metal over them. You need to make sure there is no way for water to get in there. Ill post up the pics I have on my phone and this weekend ill try to get some better ones with my digital camera.

Not my thread, but thank you as well for posting these pics. And more would indeed be awesome.
Couple weeks ago I got a really nice Hobart 210mvp and i really want to tackle my rockers and plate the subframe.
Any pics/suggestions I can find get saved for review while I'm doing this!

.030 is perfect for that kind of welder and the stuff you'll be welding (at least I assume). .035 would be okay, but it isn't necessary. I use .045 at work because I use a 480V 3 phase with 100% duty cycle. I run welds for 15-20 minutes at a time and regularly weld 1/2" and thicker. If you find that your welds seem to be kind of narrow and raised, try the .035 and make larger circles. The nice thing with .030 is that it's much more friendly with sheet metal and its easier to control.
