98 camry harmonic balancer bolt won't come off

Okay dumb question the bolt that holds the harmonic balancer on the Toyota Camry those are right-handed threads correct? If anybody's got a idea on how to get them off I sure would appreciate it, already broke two extensions

Set up a large breaker bar with an impact socket so that the breaker bar is braced by a frame member or wood on the ground or just something really solid so that when the engine turns clockwise, the breaker bar is jammed into the frame. Then blip the starter.
