“I bought this jeep in 2015 and made all repairs then. My Jeep is in 100% running condition and was driven for a year before I bought another 4 wheel drive.
It was parked for the last year and its not what I need anymore. All the drive train was inspected and repaired as needed. Brake shoes, drums, wheel cylinders, brake lines were replaced. Rebuilt carburetor, new starter, bronze radiator, Electric fan kit,
All driveline U joints including front axles U joints were replaced. 2 new truck batteries. New set of 5 Goodyear wrangler tires. The instrument panel has been rebuilt, new heater fan motor, fuel pump, wiper motor, turn signals repaired, new light fixtures, UPGRADES; vintage day lighters, bull bar, tire rack, extra roof rack, full size roll bar, fuel tank carrier, electric fuel pump, extra marine fuel tank mounted and connected . New winch, with sling, extra long steel cable, and snatch block.
In case your interested in restoring the jeep because the body is rusted but I have located a good used tub for $1250.
The Washington title is clear with current tags and in my name.”
