What up!
I have for sale my OEM open diff from my 10' 370z. I pulled it out at 34k and have it cleaned up and ready to be sold. I CAN ship this although it will be expensive as it weighs nearly 100#. It will be drained of all fluid and I can remove the diff ear bushings upon request. I'm asking $150 obo + shipping. I'll work with you on the shipping costs.
*NOTE* this diff only fits 09-11 370z. 12-14 the diff flanges changed.
