They have the dimensions for the various configs (barrel profile and distance from boss to front of action) on the page, but they have always been helpful when I called (another husband and wife shop).

Can also make you a laminated stock for it if you want or fancy walnut etc.

Don't know who makes a metal plate - should be able to fit a "generic" matal plate from brownells if you are doing a new stock. If I was doing a new stock (not too worried about "orginal" appearance since it is a new stock) I would look at the thin solid red pads like Galazan offers (midway, brownells have them).
