What do they look like?

You can kinda see them in this composite view already installed on the head.

Forget them. You don't need them. Comp 980 replacements.

Coach is correct on the 980's.....
However if you go with Comp's 979's they must be used.

What are the spring rates on the 979s? and 980s?
