Yes. Its an AAR. It was an auto car. I put in a four speed many years ago. I've had it for 40 years. I've changed motors, mounts, balanced the flywheel, changed driveshafts and even a transmission. I can't imagine that it would be my rear end. I've got another car that I am restoring right now and then I'll start over from scratch. It's better than when I started trying to find it. I just don't drive over 65. Not much help but good luck to you.
