First gen Tacoma front diff leak

I have a 2000 Tacoma base model 4x4, m/t. You lock the hubs at the hub assembly.


I noticed my passages side inner boot cover has split and I know to change it.

while looking at the cv axle I noticed that oil was leaking from the axle tube. I have to pull the axle anyways, what I need help with is where to get the seal . Some places call it a dust cover. It looks list like the out put seals on the t case. Are they the same size? Thank you for any help you can give
