Personally I am going to say it wont work as I have told a number of people.
The reason being the hump and angle off the the left side would require reshaping to fit the contour...Which isn't all that hard to do with a little boiling water and some patience.
Secondly the bolt would only contact the cheek rest on the edge of the bolt and not sit flush....Most likely a cosmetic issue to myself and most likely would not effect the overall useablity of the cheek rest.
After having said that many have still gone ahead and purchased a cheek rest to have a go at it anyhow.....Where or how it worked out I don't know as no one has ever contacted me after the fact as to it worked or not.
Just my 2 cents worth
