parts??

i have a savage 62, i was thinking of calling savage about some parts i could if needed replace myself. are there any parts resticted?, i looked on numrich for the picture of the part as i was told my gun was made just over a month ago and isn't in the savage part finder site yet. i was thinking extractor, ejector, firing pin, and magazine latch spring. i don't think i will need the hammer spring or bolt spring as they are coil and are not prone to breaking or failure. if i'm wrong please let me know. is there any other part ya'll would get in case of a problem? thanks for any help
