I am selling my 1998 GMC Sonoma, it has the 4.3L along with the 4L60-E, it just hit 176k. It does need some work as the 4x4 doesn’t work. Since I never go off roading I’ve just never taken the time to fix it. It does have a few other minor cosmetic problems but still runs and drives great. It has 31x10.50-15 laughen X-Fit At. They have about 9,000 miles on them rotated every 3,000 by myself. It does have a flow master muffler with a high flow performance cat from magna-flow. It also has a JVC head unit with kicker 75 watt rms speakers all around and a 300rms kicker sub with mono amp! As well as xenon bulbs provide excellent light. I can get more information or pictures to serious inquiries!
