Air Dam Installation

[millerje01]

I have a fibreglass air dam and want to install it on my 71 Z. Unfortunately I don't know the manufacturer of the air dam and don't have any installation instructions. I have attached pictures of the air dam.

Any information as to the manufacturer or how to install the air dam is appreciated.

My questions are:

1. Is the air dam installed with the left and right corner pieces (where the turn signals are mounted) and the center valence on the car? It looks to me like the turn signal lights are inserted into the air dam and then attached to the corner pieces.

2. Does the air dam go over the top of the center valence. My thought is it goes on top of the valence. I think the valence needs to be there to keep the air dam from flexing or deforming under air pressure at speed.

3. Does the flange above where the turn signals are inserted go behind the headlight buckets? That is between the headlight bucket and the corner piece. See picture 6 & 7

4. There is a horizontal flange at the outer end of the air dam (on both ends) that looks like it gets clamped between the headlight bucket and the corner pieces.

Any assistance or recommendations is appreciated

Answers:

1. No you must remove the corner pieces under the headlight buckets where the turn signals are bolted to. Thus removing the center valance since the valance has no place to bolt to.

2. No more center valance.

3. Yes it goes behind.

4. That flange is where the spoiler is secured to the car.

Looking at your pictures it looks like the spoiler is used. I can see where there are holes that have been drilled and the corner looks like it has been shaved.

Park you car on a flat surface. Get some 2x4's & 1x4's. Make 3 even stacks in front of your car, place them so that the bottom edge of the spoiler will sit on the stacks. Move them around and increase/decrease the height to get the spoiler to sit exactly where you want it to. If the front bumper is removed it will make installation a lot easier.

Mark the holes at the bottom of the headlight buckets. There will be two on each one. The spoiler should also bolt to your fender, unfortunately it looks like someone shaved this portion off. There are a total of 8 bolts that should hold the spoiler, four on each sided. Two on the bucket and two on the fender. Take a closer picture of the rear top corner so I can see how bad the corners have been shaved.

Once your holes are drilled I would recommend using fender washers with your bolts.
