Going Prairie Dog hunting and would like to acquire a few spare parts Just-In-Case -- Bringing a backup rifle but prefer the Savage.

I have on my list of things to get the following

Extractor
Extractor Spring
Extractor Ball

Ejector
Ejector Spring
Ejector Pin

Firing Pin Assembly -- or at least a Firing Pin and Mainspring

Am I missing anything that I should have -- will be kind of remote and would rather fix myself then take a trip.

Thanks for any help.
