That's not rust, it's Canadian patina...
For the next person looking for it.... here is how I did it.
Grind down the side of the frame where the old pipe was and get to nice steel, clean it up so it's easier to weld.
I got some "black pipe" with an OD of 1.66", I used about 42" give or take. This size will slide through the existing pipe without too much force. (one side went in really easy, the other side was a bit more difficult but I won!)
Cut the shock mounts out of the old pipe section, I used my chop saw to get them close, then a bench grinder to get them to the final shape.
Find the center point of your pipe section, and measure 10-1/4" out from center each side. This is where you need to drill through. Be sure that you drill through the center, and that you are perpendicular to the pipe so that the shock mount is square to the pipe. Also be very sure that the second hole is ligned up with the first one!. DON'T WELD THEM IN YET!!!
After drilling the holes and test fitting the mounts, slide the tube through the first side of the frame. (whichever side is a looser fit)
Once you have the tube in far enough, rotate it so that you can install the mounting stub, then weld it. (no going back now!) Weld the second stub, then rotate the tube to line up the stubs so they are paralell with the lower mounts.
At this point I attached the shocks to the top mounts, it helped to see when they were alligned correctly. Then I hammered the pipe in the rest of the way. I had about 1/4" of pipe sticking out each side of the frame, it made it nice to weld to.
