I have a 42 block in one hand and the later 98 block in the other, the only differece in the two is the spring loaded detents on the 42 block. If you take the hook from the late 98 and the 42 block it should work in the late 98 shot gun. I would rather have the correct parts for the weapon and there are a lot of the 98 safety block out there but I don't see very many of the hooks.
