Go to the Savage Arms site and there is a parts finder area where you enter your rifle's serial number in and it will show a PDF of the parts and you can order directly.
Mystic Precision is very good at having or getting pretty much any Savage Part you want. There are also three Canada Warranty outlets listed on Savages site. You can order a lot of Savage parts direct from them. I usually order from the Ontario location but the Quebec one is good too.
