it comes with linkage, everything motor swap related except the axles, i have the passenger axle still the drivers side broke the motor has good compression all the way across, it came out of a car that was vandelized i pulled the swap out and am going to scrap the car, as far as mileage im still trying to get the exact number, the cluster was damaged when the car was vadelized, nothing was touched on the motor so no worries about that
