Engine Inlet Adaptor: Tfs Or Edelbrock?

Is there any difference between the two inlet adaptors or are they both pretty much the same? They're about the same price.

I'm partial to the Edelbrock part since their stuff is supposed to be made in the US, but TFS might make theirs here as well. I'm also hoping to match the color with a factory painted Lightning upper, so if they're both pretty much equivalent parts would one match the GT40 aluminum/silver better than the other?

Here are the three I've been considering:

TFS Silver Powdercoat

TFS Natural Aluminum

Edelbrock

It's difficult to tell from the pictures, but the TFS parts look like cleaner castings on the inside. It also says that they support 75mm throttle bodies. Maybe the way to go is to get the natural aluminum TFS part and paint it to match.
