Are they completely flat on the bottom? or are they concaved?

Are you refering to the front or rear spoiler? I have both on my 1970 and there are no flat surfaces I can think of.

I have an original front BRE spoiler and it has no flta surfaces on the bottom either. It is open.

The rear, sorry.

The reason is, I want to put one on a different kind of car, if its flat on the bottom, i can do it.

Flat... hummm

Well actually it is not flat... it curves over the body line of the Z - righ tto left. Front to Rear of course it follows the body line, so it sits at the angle it's supposed to. There are too flat spots if you will, in which studs are mounted - these go though the deck lid - and are secured by nuts from the underside.

Nonetheless - it's fiberglass - and you can easily cut/mold it any way you want...

FWIW,

Took the words right out of my mouth Carl....I'll second that thought regarding it being fiber glass and easily modified.

One more question, anybody have a measurment for how long the wing is?

Well, I suspect if you measure how wide a 240Z is...

All together now........DOH!

This is a SWAG but, it's most likely 2" to 3" shorter than the rear end is wide.
