What happened to the NearStereoFarMono Unity sample?

The scene / prefabs and materials for the sample Mono Optimization seem to be missing from the Unity Sample Project 1.27 and up. Only the scripts and shader remain. I tried using the missing files from 1.25 in Unity 2018.2 but they dont work properly. The left eye works great but the right eye is offset slightly wrong and I cant seem to fix it. Could that be why the files have been removed from 1.27-1.28?

I've tried messing with the old files in all kinds of ways to try make it work, but ive only succeeded in making the problem worse... -_-

Might anyone have any insight on what happened to this rendering technique or better yet, how to get it working again?

Thanks :)
