I did search the forums for the info... really.

I have a Model 12 FLV in 204 Ruger (.378 bolt head) and, thanks to forum members, a small assortment of barrels chambered for cartridges based on the 308 Wnchester case.

I have a stripped left hand short action .473 bolt head bought through Midway. I know the best way is to buy the small parts and just swap out the complete bolt head.

Can I just swap the ejector and extractor parts over to the .473 bolt head, or are the parts a different size?
