That's a screaming deal as it is (don't tell the seller that, though ) cracks along the grain aren't that big a deal, in my astonishingly humble opinion. Easily repaired and you'd never even know it was there, and like a fractured bone, once it's healed it will be stronger than it was before.
Option one: send it to the mothership. It's worth every penny, because afterward, every time you open the case and gaze upon gleaming perfection it'll go right to your backbone. You'll be able to play stuff you never thought possible. People will weep and you'll become rich and famous. You watch.
Option two: take it to a repairman of repute. This is the Alembic Club, we can recommend people in your area. We know stuff.
If it was a mass-produced plank, me and others would tell you how to patch it back up and get back to playing those Journey covers, but it ain't. It's an Alembic, the highest art in musical instruments, up there with Steinway, D'Angelico and Amati.
Just my opinion. I'd snag that baby myself, if I could afford the ensuing divorce.
