How to do Conical Gradient in illustrator

[UltimateGraphics]

Hi,

I have a customer that wants me to redesign his logo do to him having problems with his last graphics company. (you will see in the picture why).

I have the logo all design expect for the conical gradient. I used a different gradient but he insist on having it in there.

Attached is the picture of his logo on the truck.

Can some one tell me how to do it like that?

Thanks!!
