So I went to check out a "YS1 LSD" trans, and upon looking in the axle hole, I seen something odd. I've never seen a LSD like this before, but the guy swears it's an OEM LSD. Maybe the early cable trans had these? you can see through to the other side, although it's through a small hole, rather than being able to see through a hole the same size as the splined axle holes. I've never seen anything like it. I'm hoping it's not some cheapie OBX crap.
