Hunter's suggestion to turn the scope is spot on for a side-mount on a 94. But try turning it a full 90deg (quarter turn) instead of just 45.
Your elevation knob becomes the windage knob and vice versa.
For the screws if you do decide to remove the mount, check with a local gun smith or post up some pictures of your mount.
There are several different side-mounts for the 94, and I suspect most of them mount to the same holes but there might be an oddball out there.
If your mount is attached to the receiver-sight (peep sight) screw holes on the side of the receiver, those should be 6-48 thread. The front screw on the Weaver side-mount attaches to the cartridge guide screw. All of those should be available at Brownells, NumrichArms, or maybe even a local shop.
