This diff came out of my 76 280z.  Not even sure what diff it is.  Anyone know what it is and how much it's worth?





unbolt the cover and read the stamp on the ring gear (that giant circular gear). That will give you the ratio. OEM S30 diffs are sold as either an R180 or R200, and a gear ratio. You have an R200. You can’t tell the ratio unless you unbolt the cover or count the number of turns  manually. It will likely be a open 3.545.


people who are willing to pay top dollar will need to know the ratio.
