If you called them I'm sure they could tell you for sure but I would assume (probably wrong) that yes they would work just fine. I have in the past used large ring 98's to build .308 Win. rifles and used the original extractor and it worked fine. Of course I did the extractor test. They also make one that has to be fitted. I have accumulated several military 98 extractors over the years as spare parts but I also keep one new 98 extractor just in case. I assume (here we go again) you know how to check the extractor on a Mauser type rifle. There's nothing wrong with re-working a extractor to over ride the rim as long as you know what your doing, they work just fine when done right.
