[NOT A TA]

The Turbo hood is a little shorter (1/8"-3/16" maybe, I forget) so you end up with too wide a gap at the leading edge of the hood when the rear edge is aligned properly with the rear upper edge of the fenders at the windshield base. To solve that you need to add a little to the front edge of the hood or the rear edge of the front header. Welding a bit along the leading edge of the hood wasn't an option for me at the time but would give a "cleaner" look.

The center section of the Turbo hood is also higher than the center of the Malibu header so you have to add height to the header so they match at the leading edge of the hood. The body lines in the hood and header also will not match up (off maybe 1/2") Since I was already adding to the header and making a new body line I used that opportunity to build back a bit to narrow the gap between the hood and header.

If I remember correctly (was over 10 years ago) I think the rear corners had to be "massaged" to lay flatter so the rear edge of the hood would run across to the upper rear corner of the fender at the windshield base.

The hinges, bumpers, and hood latch match up fine and I drove this car as my daily driver for 11-12 years with the hood before deciding to put some new metal in a couple rusty fender and door areas and paint the car again.
