I'm inclined to agree with you about the x member, and we welded all the rivets as well. But having now welded the x member, we find that the frame won't twist at all. This is not to say that the application of a few hundred horsepower won't do the trick.
Since I am at the other side of North America from you, I will ask the local rodding crowd if they know of the moulding you seek. Do you happen to know if the 33 and 34 mouldings might be the same?
