Pitman arm is hitting tortion bar! Help?

I will have to post a picture of that tortion bar for everyone to see. Now im not sure if the car was wrecked or what happen to it but you can tell the drivers side frame has been welded on in one spot. Yes i did look at the numbers. I actually just took a micrometer and measured my other tortion bars they were .85 and that is a 318 tortion bar if im correct. I have two 318 tortion bars and 2 slant 6 tortion bars. Do you guys think the 318 one will work for now or should i order a 340 one immediateley?
