I did however revisit a link that user @DionR sent me a while back, Hooker Blackheart part number BHS578. That is the upper crossmember hoop to be used in a Gen III Hemi swap with a NAG1 transmission.
There is also the BHS588 bolt in brace. No idea if it would fit with your kit, and you already bought the other part, but just tossing it out there.
I don't really like it just based on the thought that (in my mind) you should de-tension the TB's if you want to drop the crossmember. But maybe it is useful otherwise? Guessing Holley has the budget to actually design it, most of their instructions show images that imply they have full blown CAD models of most things so an analysis of the truss might be as easy as modelling it and pushing a button. So, in theory, it should do the job of replacing the upper part of the crossmember. Just comes with some overhead I wish it didn't.
