rear frame crossmember

I have installed a 70 mustang gas tank in the rear of the frame and need to replace the rearmost crossmember, I have it but it was not attached to the frame when I got it. My question is since the crossmember has a curve in it, which way does the curve go, up or down?

I'm intending to do this mod to my 51 - does the rear crossmember have to be welded in place...or is it actually better to bolt it in (I believe it is currently riveted in place in the stock frame) or does it make any real difference in a practical sense? Thanks!

when i put my mustang tank in the rear cross member had to be moved back.
i was going to weld it in but it has to be removed to get the fuel tanks out.
so bolting was a better option.
