I've examined the hood on an SVT very closely.
The hood is about 1/2" too short from front to back and about 1/4" - 1/2" too narrow.
If you pull the hood forward to line it up correctly with the oval and headlights, it doesn't line up at all by the cowl. And vice-versa. You just have to find a "middle ground".
The width can be "fixed" by adjusting your fenders.
Unfortuantely, when a mold is used, it's tough to get it exactly right.
