Default Factory 3.08's?

Does anybody know if the factory made NBS trucks with 3.08 gears? I know the aftermarket makes them but was it an available RPO for 8.6" 10 bolts?

Interesting....and from what I've gathered, 8.6 and 8.5 rear ends have identical ring and pinions.

Im almost positive I've seen it. Im pretty sure they only put them in RCSB V6's. Never saw them in a V8.

Can you get any part numbers off of them? You wouldn't be willing to let those go would you?
