What rear end ratio do I have?

Searched other threads and it looks like I either have 3:73 or 3:08 gears in my 71, auto trans, 4 x4, Blazer. At first, I thought 3:73 was what came from the factory unless you ordered another ratio. However, I've seen a few SPIDs that listed a 3:73 ratio as if it was ordered as an option. Assuming I have the factory stock rear end, what would that ratio be? Thanks.
