Rib with pork belly attached, how to cook? See pics

So this is the side ribs with the belly and crackle attached, after some consideration and consultation, now think it is the best to do 5 hrs low and slow and introduce some liquid to the drip pan in hour 4 to semi-steam the beast. Idea is that the crackle should pop if i keep it at 250 because its on for 5 hours. Any other suggestions or hints would be welcome.
