There are 3 cases for the g260. Some only have the early socket cap screws that hold the shift plate, then there was one with both mounting locations, then the latest ones have only the late style mount and the holes for the socket cap screws are not tapped but can be to accept the early plate. If you use the one with both mounts, you have to make sure to put screws in the early holes or the fluid can come out of them when using the late shifter.
