I have never seen bone in pork belly. When I cook pork belly I do bacon bites. Very simple to do.
1. Cut belly into 1 inch strips
2. Soak strips in water for 3 hours to remove salt (optional)
3. Put on smoker @ 275 for 1 hour. Turn strips over
4. Smoke until temp reaches 200 degrees
5. Add BBQ sauce and pull after sauce tightens up
6. Cut into cubes for serving
Of course in your case you couldn't cut into cubes. I guess yours would be bacon strips.
