Need help with vibration!!

Sorry it does vibrate in gear going down the road, but not when in neutral sitting in the drive. That's the only thing I have changed since last yea r is the motor and I assume that's my problem. I had clutch out and checked its fine, but now if I have flywheel balanced could it effect anything else? Like is it possible it could get worst? It has a 360 dampner on the front and I saw and have my balancing sheet if that helps ? I don't know how to read it and I did see where crank had Mallory metal added in the rear of crank
