Are you absolutely sure that's the bolt pattern you have? Thats not a standard wheel bolt pattern so I'd be inclined to believe you have either a 5 on 5 inch or a 5 on 5-1/2 inch. I attached a picture that shows how you can easily measure your bolt pattern to verify. Let me know what you have and we can go from there.
