You will need to create a Stock solid to make this easy
To rotate the stock to the correct angle you can select the "side" UCS for the plane that you want to rotate the stock in.
Next go to the "Rotate" utility under the "Utilities" Tab, now where it says "Angle Around Axis" type 15 in the Z axis box, now left click on your stock solid to highlight it, it should go Red, now right click and select OK and you should get a preview of the new position of the stock, if it is what/where you want it then just click OK again and you are done, then cancel the Rotate Utility.
Hope that helps
Regards
Rob
