Hey Coker, Those look to be in pretty good shape, I'd fix them for sure.

C20's had plates attached to the top and bottom of the trailing arms to keep them from separating. You could modify yours in a similar manner. ECE used to sell a kit to retrofit the plates to existing arms but i don't think they are selling them anymore.

Here's some photos of C-20 arms and some links for ya:
