As to the original poster I have no idea if your even remotely still interested but I will tell you this, with the right bargaining skills you can do one yourself for around 1k not sure if you still have the car but I would recommend picking one up that is already done you will get off super cheap as no one will recoup the cost of building one of these beasts. but as I see we are all flaunting here all share with yall what I have in mine and I would like to add a shout out to the USAF for every one of my pay checks goes into this dam addiction.
