Implementing distance Grab with Unity 2017?

Does anyone know how to do this?  There is a distance grab sample on the Oculus sample framework package, which is intended for Unity 5.5/5.6. I get compile errors when importing the latest sample framework into unity 2017.  I cannot use an older version of unity because i have some assets which require Unity 2017. Does anyone know how to build the distance grabber from provided scripts?  Thanks
