Corse I CV joints

[hollytree]

The original inner and outer joints both had single circlips on the drive shaft with 2 holes in the end for circlip pliers.
The new inner - Alfa - came with the same style circlip.
The new outer - Ford - came with something that looks like a concave thrust washer and a circlip without any holes.

Does anybody know what I do with these 2 parts, or do I just replace the original circlip?

EDIT
It is for certain applications, but not how I will be using it. So original circlip back on.
