360 balance ?s

I have had quite a vibration. I checked to see if I had a 360 converter. I believe I do, as it has a large weight on it. I also looked at my damper. Which I believe is fine. And it.has a recess in it. My questions are.
1 is it possible to install the flex plate backward?
2 is the weight supposed to be aligned with the recess?
the weights are on opposite sides. Should the heavy side of the damper be opposite the weight?
