Thanks Derrick and Triaged, I` talked to a very knowledgeable sales rep at Summit this afternoon and he asked me to count the bolts. He said that if I have the 14 bolt it's a Chevy but if I have 12 or 10 it's a Dana. My count is 12 so I think he said that it's a model Dana 70. I'll get back with him today for the follow through.

 

I couldn't hook up with my original rep at Summit, and the one I got said that he didn't have enough information. He needs me to pull an axel and count the splines. He said that the 12 bolt differential of that year had 2 different spline setups..

 

Dana 70 will be a full floating axle so pulling one is simple. You don't even need to lift the tire off the ground. Pull off the center cap and there will be 8 bolts holding the axle on. Take those off and the axle slides out. Put something there to catch the oil.

 

Thanks Triaged, that sounds a lot easier than I thought.

 

08 is old enough to watch the junkyards for a G80 rear.

I had a 2002 with one and junked it a couple years ago.

 

Thank you William. That's a good idea. A junk yard rear end is less than $200.
