Question for all the Mauser experts. Will 2 peice scope bases on a 98 work on the 1908? I have a 1908 that came in my shop with stripped base threads and no bases. .440 hole spacing on the rear and .860 hole spacing on the front of the receiver. The front receiver ring is higher than the rear. I don't normally work on these, I'm just trying to help the owner get his rifle working.
