Your front is a low pinion, standard rotation D30. Rear is one of two, D35 or D44a. Both rears are c-clipped and not considered great for more than a 33 open. The 35 is the smaller of the two and the 44a (not to be confused with a D44) has an aluminum center section. Most V8s came with the 44a. If you can post a pic of the diff cover you'll get a definate answer.
