I just ordered a pair yesterday from Dean at Datsunparts dot com. He is asking $130/each, or $230/pair. He just got his first shipment of 15 pairs. Datsunparts mostly caters to Datsun Roadsters, but he has other parts as well, and apparently specializes in remanufacturing NLA Datsun parts. I will let everyone know about look and fitment after I receive them. Here's the link to his website: Datsunparts.com Partnumber 2550 Datsun Z Car 70 - 78 & 510 68 - 73 Rear Aluminun Finned Brake Drum Be aware that he only takes orders by phone or e-mail, no shopping cart.
