1998 GMC Sierra K3500 4X4 Turbo Diesel Dually

98 GMC Sierra SLT k3500 Dually 4x4 6.5 Turbo Diesel. 236k Runs and drives good. Trucks straight and very presentable. 4l80e auto trans shifts great. Cold A/C Everything works power windows, locks, seats, cruise, all the lights inside and out working. Remotely mounted pmd trucks completely stock. Engine rebuilt 50k ago builder tags under the hood but previous owner could not find paperwork. No cold start issues always fires right off. Recent work new starter, new delco a/c compressor blows cold, serp belt, new front brake calipers, new batteries, oil change, recent tabs. Some issues are the fuel gauge is accurate most of the time but it pegs full occasionally and the speedo is off by roughly 12mph I’m guessing the cluster it’s a cool old truck Clean Oregon title Serious interest please thanks.
