I have (2) ARB RD03/127 air locking differentials that I was going to use on a Series II restoration. Plans have changed and I am parting out the Rover instead. These retail for anywhere from $800-980. The boxes have not been opened except to take a picture recently and they are factory sealed. If you want to buy both boxes, make me a reasonable offer and I will cut you a deal. I will promptly reply to your email. Cash or PayPal please.
