The 2-hole variety with one screw in the middle of each end of the housing are a standard format. If your tuners have one screw pay very careful attention to the position of this screw.
There are 4 different positions this screw can be in depending on the brand of tuners and if you choose a set of tuner with the correct screw position it will eliminate the need to drill new holes in the guitar. The position of the screw is indicated in the description and can also be seen in the photos. If your tuners have a screw position that isn't available you will need to drill new holes to install a new set.
