Hello, I need to replace the inner front axle seals, left and right wheels, on a 37 Caddy Fleetwood 75 series. The old ones appear to be felt, but old, hard and leaking. NAPA said that they do not have a listing for this part. I think the seals come in contact with the outer part of the inner wheel bearing which has the following part number of it: 909528. Any help on where I could obtain these seals would be greatly appreciated. Joe
