I can't give you total confirmation on the 935, but the base does fit the 1/2" center to center hole spacing on the 835 without any additional drilling or tapping. I assume they will be the same.
Just measure your hole spacing and if it's 1/2", you're good to go. Hope this helps.
But you will need 8-40 screws to fit the pre-drilled holes on a Mossy, the screws that came with mine were too small.
