Has anyone successfully used the USCartool A500 Crossmember?

I'm kind of skeptical if that 1/4" bar is really enough, it would be better if it was a box structure like the original for sure. In bending "cross-car" (think passenger side to right side as arrows show) with stress from the suspension rising and falling, I doubt it has much strength. The floors have very little strength outside of the crossmember.

Well, I'm kinda just winging it, based on what I've seen other people do. I've read every thread I can find on this swap, probably multiple times. I realize the channel shape of the original member is probably stronger, but fact is it has to come out to do this swap.
When I do my next test fit of the transmission, I'll see how much room I actually have above the tranny. I could add some metal to the edges basically making a channel out of it, but it would still have to be shorter than the original.
