After seeing Land of the Dead today- (fun, not great, some good bits, some silly bits, worth seeing though) I fired up the jeep and threw it into gear (on stands)
Only the left hand wheels got power. The front right was dead, and the rear right was turning in small spurts of power.
I think there is some rust in the gas tank so tomorrow I am going to try and use the old acid cure myself. Slosh it around with some brass chain I have. Then flush with 10,000 gallons of water. A friend is looking at a 1942 GPW this weekend, and I offered to go with him. Watch it be the first WW2 jeep I owned and sold as parts long ago.
