I did something like that with my upper shock mount. I was thinking you might want to put a gusset on that?? Maybe not....
Do you have any bolts going through the crossmember into the side rail? I've been thinking (I'll have to wait until I get my frame back) that maybe I can make a bracket for those holes that stick up past the top of the frame to connect that part of the crossmember to the top of the frame.
