I recently picked up a 35 Packard project car. I bought it as a roller, with the stock front end and rear end. The rear is something I have never seen before. From the back, it looks like a Ford 9" flipped so the back is facing the bottom of the car, but the pinion is facing the front of the car. I hope I am explaining this correctly. Does anyone have any familiarity with this rear end? Is it usable for a driver, or should I pull it and use a more modern rear like a Ford 9"? I am just putting a plan together for the car, so I haven't dug into it yet.
