We just went through this a week or two ago. I think it was determined that an 8.2 10-bolt has a 1 1/8" pinion nut, while a 8.5 has a 1 1/4" pinion nut. Someone posted a web link that also showed some minor housing differences, but the pinion nut seemed like the easiest, most verifiable way without having to open it up. (although you'd have to remove the driveshaft)
