Well Over 45,000 invested in this truck. The truck has everything shown above & is in great shape. It will, however, take some time playing with it to get everything dialed in just right - if you want it to run 10s. Unfortunately for me I can no longer have this truck. I need to sell it. The truck was listed for $21,500, It has been working it's way down & is now for Sale for $17,000 with everything or $16,500 without the extra wheels & tires & the DFI. Please email me at djstanke@zenithtechinc.com or call me at 414-704-2484.

I would also entertain a partial trade of 86-87 GN or T

The T would have to be white or gunmetal.

Stock or modified - car + cash.
