When you finish adjusting the brackets, Don't Close The Hood, instead lower it slowly and make sure that it does not chip the paint on the fenders.
You need at least one buddy, but two would be better. Get a fine line majic marker and draw a line around your hood bracket bolts (4 ea on each side) that attach to both the hood and the body of the car.
This is the refference point and you can return the brackets and hood, to this location, if all future adjustments fail.
Here are the 2 proceedures that I used when I installed my non-oem hood:
1st
Loosen the brackets that bolt down to the body of the car. Slide the brackets (with the hood still attached) towards the headlights/bumper, as much as possible. Then tighten those bolts.
Loosen the bolts that attach the brackets to the hood and slide the hood as far forward and you can. Then tighten the bolts.
Don't close the hood! You might have shifted it too far, to one side or the other, and you will chip your paint.
Gently lower the hood and verity that it will not make contact with your fenders.
Loosen and tighten the hood to bracket bolts as necessary, to prevent painmt chipping.
Once you get it lined up, as good as you can, you have to look at the hood next to the windshield. Does it look like its lines are flowing or have you moved the hood too far forward? I was able to slide my hood even farther forward, without effecting the lines, but I had to file out my brackets, as mentioned in the next step:
2nd
This is the getto style the nathon_carmona is refering to:
If the lines look ok (by the windshield), but the hood still needs to slide forward, there is one more thing that you can do.
Remove the 4 bolts that attch the brackets to the body of the car and lift the hood completely off the car.
Put the hood, upside down, on a thick bedspread and get a 1/8" round metal file.
Each of the brackets have 2 holes where the 'body' bolts go.
File, no more than 1/4" off of one side, of each of the 4 holes. The hole will become more oval in shape.
The side that you file (enlarge) is the edge of the hole that will be closest to the windshield, when the hood is closed.
Bolt the hood back on the car and slide it as far forward as you can, and tighten up the bolts.
Gently close the hood and see how much you need to adjust the brackets that attach to the hood. (you should not need to readjust the bracket bolts that you filed out.
You may have to readjust it a couple of times, but if you don't like lyour results, you can return the bolts to the original majic marker marks, which you made.
