Anyone Install a Locker?

From what I've been reading more of the 373"s are, the lower ratio not as much, but it all depends who ordered what on their new vehicle . I'm sure their were many that ordered a big block Chevy or Ford, and didn't want posi back in the day. Should be a tag on one of the diff bolts that will say 3L73 if limited slip. Like you said Henry, theirs a website that helps decifer your door sticker as well.
