The clips are only for the throw-out bearing, they hold the bearing onto the fork. If the clips break or fall off, the TO bearing causes troubles, what troubles I don't know specifically.

 

The pilot bearing has no clips, it sits inside the flywheel and it held in place by friction until you mate the engine and trans then it's pinned between the input shaft of the trans and the back of the crank.

I figured as much, thanks! So yeah, I guess once those parts come in next week it's time for the install...
