STATEMENT FROM THE CURRENT OWNER:
The truck is driven only in the nice weather and stored in winters. Originally came from Texas so it is a rust free body. There have been extensive modifications to the drive line but the body was left stock except for a cowl hood.The interior is 100% stock and in very nice condition. The mods that have been done were completed in a way it could be easily put back to stock. It has been converted to a LS power plant with twin turbos, but still retains all the comfort and driveability of a stock truck with A/C, power steering, etc. The transmission was replaced with a 4L80E Automatic and the rear end has been upgraded to a GM 12 bolt with coil-over suspension.
