Installed Direct Connection chin spoiler...flex???

Are those chin spoilers available, like re-pop or anything. After seeing this post I kinda want one for my 73 dart which is the exact front end.
Here's a direct link from Bob's suggestion:

70-73 Duster spoiler

Hmm... the way Randy suggest mounting his has them sitting much deeper...using the radiator support? I don't think that's the intended location on a big bumper car...but I'll have to take another look.
