Any Tesoro dealer should be able to order you one in grey. I copied the below information of Tesoro web page as you can see the covers are available in brown and grey. I have the size small brown one on my Outlaw they also make the large size for the Tejon in brown or grey. I got it from Rusty Henry Tesoro service manager. He is also an independent Tesoro dealer Rusty detectors in Prescott Arizona. You could call him at Tesoro and get his personal business number and then call him after hours. He does not do any personal business on Tesoros time but he will give you the number to call him after hours can leave a message and he will call you back.
