The same bridge design this guitar ships with, so it should bolt straight into the existing route and studs. The stock one has stainless steel screws, which you can reuse if you want to keep them.
Why we say this
ESP describes this guitar's stock bridge as a Floyd Rose Original upgraded with stainless steel screws, so a standard Floyd Rose Original is the same design and footprint. Floyd Rose Originals have a stud spacing of about 74mm and a 12 inch saddle radius, matching this guitar's 12 inch fingerboard radius. The stock bridge has stainless steel screws, which the standard Original kit does not, since Floyd Rose sells stainless upgrades separately. Not measured on this guitar.
