Let's not forget that as the cost of production goes up (labor, regulatory compliance, etc), the profit margins get thinner and thinner. Costs end up getting cut somewhere. It gets really easy to see why a lot of this **** gets outsourced oversees.
I've had good luck with Engine Pro sets. I've only been able to get them through engine shops though.

Can you drill and tap it in place? It'd probably be a total pain in the ***, but possibly doable. Just raise or lower that part to where you can get a straight shot on it with a drill. Hell, if you mess it up, maybe a through bolt and nut on the backside would work.
I don't think it's the copycat **** that's getting them in trouble. It's the fact that they actually put the dude's business name on it. Dude's lawyer should have a field day with this one.
If you can get get the broken piece out, I'd just cut the head off that bolt in the picture and use the washer along with a new bolt. Of course, you'd still want/need two thick paper gaskets and a small piece of rubber hose to mount the glass. Not the end of the world at all.
And to think, when I was just getting into Mopars as a kid, these types of discussions were reserved for the E/B-body crowd. I'd never imagine A-body folks needing a correct exhaust heat shield. Don't forget your roots, guys. :poke:
Seriously though, I wonder how many of these are sitting in...
