Man no clue what that went to, But I'm sure someone, somewhere is cringing in disgust it was cut up like that. Much as I am!
My Crower measures damn near 5" from inside one throttle bore to the other side of the other throttle bore at the back........

and from front to back should actually fit with some machining and have some extra room.

Unless your friend has some better ideas, I don't see it fitting very well at all short of machining most of the bottom of it off and welding what I have welded to a plate (Cutting the plate off) to it. Shame, as it really looks a LOT like a Crower Hercules scoop, just a lot smaller and without the ribs on the top.
Lemme tear the scoop plate off and get you some more pics with a tape on 'em to maybe see if he can work on this.

Here they is........Actually, more I look at it, might actually be feasable........


2 focked up original scoops from 2 different things to make at least 1 old school looking piece! Thing is, the piece I have is Magnesium, and I see now is only JBWelded to the plate so a couple smacks with a hammer and it's off.
