How to instantiate an object with a one specific rotation from another object

Ok so i'm creating a vr game and i'm trying to spawn an object based on the right remotes specific Y axis rotation and 0 for the X and Z axis. Currently i'm doing this,

Code (csharp):

1.  
2. Vector3 pos = new Vector3(RightRemote.transform.position.x, 0, RightRemote.transform.position.z);
3.             Instantiate(Fissure, pos, RightRemote.transform.rotation);
4.  

so basically I want to do this: Instantiate(Fissure, pos, (0, RightRemote Y axis, 0)) IF you know the syntax for this thanks in advance for the help!

 

Something like this maybe? :-

Instantiate(Fissure, pos, Quaternion.Euler(0, RightRemote.transform.rotation.y, 0))
