looking at 85 runner with a auto trans. wondering what opinions are of the auto in that truck. truck has low mileage 139k and all rust has been repaired. the guy wants 8k for it. Im thinking its probably a dog on power. how hard to convert to manual?or is the auto ok? would that mean new shafts,crossmembers,prob. center console. truck has mild lift with decent 31 inch tires.what attracts me to it is it has a decent body.
