One Hole 4570 - the standard scope mounts for a 98 Mauser should fit the Yugo 48/48A without problem - both are 98 actions with the Yugo being slightly shorter - but that isn't any problem when you have the action drilled and tapped. I would look in the Brownells catalog as they should carry the mounts you need, and I would also call to make certain they will fit your rifle. I have found the folks at Brownells to be very helpful.
