Looking for a 188mm LSD center section for an E30. I just need the center section without gears. I'll be rebuilding the diff so it doesn't currently need to lock up. Apparently there's a difference in the center section of 188mm LSDs. The center section would be for a 3.46 so it would need to be from a 3.07 or above. Shipping would suck so the closer to Philly the better.
