Brent,
It takes some work but it is relatively easy to get the stock dimensions that you may want right from the pictures Michael posts.
The short story is if you have a CAD program, like Draftsight which is a free download, you can insert Michaels picture into the CAD program. Then use the CAD program to measure one known dimension like the action or barrel length. Now comparing the actual real life dimension to the CAD dimension scale the drawing so that the picture in the CAD drawing is full size. Then it is as easy as pie to measure any feature of the stock you wish.
Now it sounds complicated but really isn't, just a little reverse engineering.
