Pie cutting the upper control arm?

I don't have any pics of mine during the process. What you can do is make the cut and air the truck out (put a small piece of wood under the tired to make sure you get enough space) then air out the truck. It will close up the space and then you can weld it up. I want to say mine was done around 1/4'' but I don't remember.
