Front spoiler on a '74L

I recently purchased (for a price I just couldn't pass up) a front spoiler for a standard narrow body car, '74L.

It is the small chin spoiler that looks like a mini version of what is on a GT5. It may be like the one on ShotgunGrooms car (Although I cannot be sure from the small photo under his moniker). It has two round holes in it that could be for brake cooling ducts (Although I suppose I could use them for fog lights).

1) I would like to get some ideas on how it looks on a narrow car. I may or may-not install it.

2) What colour looks better - black or body colour?

3) How do you install it (attach it to the car)?

I would be grateful if anyone with this type of spoiler would post some pictures.

Thanks
