Giobeast 200 rear shock replacement?

[suprf1y]

My son and I went for a little trail ride after supper last night, and at the furthest part from home, he had a catastrophic suspension failure
The rod on the rear shock broke, pulled out, and he was sitting on the rear tires, skidding along the trail.
We were able to stick it back in, took the (smooth) road home, and we made it.
So he needs a new shock.
Has anybody found, or know of a suitable replacement?
Its 11.5" eye to eye.
