Need advice on which rear axle bearing seal to purchase - 64 Chevy C10

[elane352]

Greetings,

I made the mistake of purchasing the wrong bearing seals for my application. I am hoping that someone can educate me.

When I purchased the truck, the rear was converted from 6 lugs to 5. Since I want to replace my axles, I am opting to also replace the bearings and seals. You can see the installed new bearing in the first picture.

On the left side of the second picture you can see the slightly distorted seal that I removed. On the right side is a new seal (63 - 64 Chevy C10) that I ordered from Classic Industries which does not fit. The part # is W8477. Notice the difference in shapes.

I believe that the normal/standard seal for a 64 C10 is not what I need for my setup.

Thoughts? Let me know please. I am happy to provide more pictures if needed.

Edward
