31 Model A rear end seals

[Cpuckett]

Hello, I’ve pulled the left side axle housing off and removed the entire axle. I’m wanting to replace the seals to keep the rear end grease from leaking into my drums. I have the 2 correct seals I believe. They are about an inch to inch 1/4 in diameter, red on outside with rubber on inside but I can’t figure out where the old ones are at to remove those. Thanks in advance
