Change cylinder head seal

Hello chreisler screwdriver, have bought for my girlfriend a cruiser with defective head seal and step on the spot at the moment. Have read me during the timing belt change. My problem, have the motor mounts on the steering belt side released, but the engine can not be lowered because there is still some bracket to which I can not really get to. Will the engine on both sides solved and lowered ? I am grateful for every tip Greeting Dirk
