VAILABILITY: (updated Jan. 20th, 2012) Good news and bad news: GOOD: We have an order for these motors, and we will get delivery from Mattel. BAD: We don't have shipment confirmation of this order, and we don't know when they will be arriving (and available here). Hopefully, we will know more early next week (Jan 23-24). We do have am-0912 in stock, and it has the same mounting and shaft geometry as this motor.
