71 C30 disc brake help needed!

[swarm49]

Hello, I am new here but have been working on my 71 C30 flat bed for much of the past two years.

Many many things have been completed but I am trying to replace the front discs and have realized I need a few small parts.

The link above is the disc that is on the truck now, and the one I am replacing.

What I need is a new grease seal for the back side of the disc bearing assembly and a grease cap for the front side. The caps that came off seem to be 2.5" OD dust caps, the grease seals are 3" OD, 2.25" ID (approx) and 0.48" width, any help is much appreciated!
