I have this front body kit piece on my 73' 240z, and it has odd handle or lever tyle pices or both sides like fog lights. but i am a new comer to additions or options to the Z can anyone tell me what this is, it is in my avatar picture.

What does it do, and can i add foglights to this area?

And also can anyone tell me the original size of rims, and tires for the 240z and at what limit do you need to adjust the speedo.

Thanks in advance

If it's the kind of spoiler I'm thinking about then those "handles" are the pockets for the turn signals. Here is a picture of mine that will hopefully help. If it's not the same please post a picture. The pockets below the turn signals are designed to be used as cooling ducts for your brakes but people have used them to install fog/driving lights. Do not trim your spoiler in any way until you are sure that it is secured properly to the car.

nice Z no it looks more like this..its like a "T" shape piece

i cant upload a pic so i will change my avatar look there:)

a T-shape?!

um.. your avatar is awfully hard to see... try Putfile.com or Photobucket or somethin

or use the Classiczcar.com gallery

I looked at the larger pic in your gallery, but it was still hard to tell what they were. They look vaguely like hooded license plate light fixtures, but they might be intended as some kind of a bumperette or something. A close up would be helpful.

Are you talking about the metal brackets that go down and back and bolt to the frame? Those are not part of your spoiler but are bumper brackets.
