Gas turbine engine and method of disassembly

A gas turbine engine includes a central body support (62) that provides an inner annular wall for a core flow path. The central body support (62) includes first splines (78). A geared architecture (48) interconnects a spool (30) and a fan (42) rotatable about an axis. A flex support (68) interconnects the geared architecture (48) to the central body support (62). The flex support (68) includes second splines (82) that intermesh with the first splines (78) for transferring torque there between.
