Kevin (Kejross) made his own, not a very active member anymore, but if you send him a message he may get back to you on the specifics. He has since sold the car and moved on to other projects but I'm sure he could give you some info about it.

^ His build thread on the car, again... since been sold and the new owner isn't a member here I don't think.
