UPDATE. :-(

Just received my $150+shipping Edelbrock 7577 intake manifold BOX.

Inside the Edelbrock 7577 BOX was a Mopar Performance M-1 Magnum intake.

Definitely not a great deal, definitely not ideal for my D350, and I'm gonna go ahead and guess that there's no way I can use the factory A/C brackets. (?)

Well, crap. Time to get the wallet out again.
