I purchased this wonderful car from the original owner on 10/31/1999. It has always been garage kept. It was 100% stock when I bought it. Now it has had a lot of modifications and I hope they are considered upgrades. A few years ago I did a LS swap and installed a 2002 5.3 and 4L60E out of a Silverado. They had 101K on them at that time and looked brand new inside. I installed a LS1 intake, Holley fuel rails, stainless headers and a custom wiring harness & performance tune by Affordable Fuel Injection. The stock Powerglide shifter has been converted into a 4 speed shifter with a kit from Shiftworks. The factory 10 bolt got an Eaton posi unit and Yukon 3.73 gears. The car cruises at 2200 rpm at 70 mph and gets 25 mpg. Dakota Digital VHX gauges keep track of all of the engine functions. It has factory power steering and 4 wheel power disc brakes by The Right Stuff. It has a Kenwood stereo with amp, dash speakers and 2 Cerwin Vega 6X9s & a 10" sub in the trunk. It has 17" American Torque Thrust wheels & Kumho tires, KYB shocks in the front and Gabriel Air shocks out back. I will be glad to answer any questions I might have forgot through the ebay message system. Thanks for looking and have a great day
