new lens or body?

You need a spare body, and the 5Dc is super old now. Body for sure.

Agreed. If you're getting paid, or if people are depending on you to get the shot even if you're not getting paid, a backup body is a necessity.

I'd agree with this philosophy. Not having a backup body could be a serious achilles heel. The first time you tell a bride "I'm finished because my camera quit" is probably the last job you do.

I once had two cameras fail on the same day. I worked out later it was because I cleaned the contacts with an inappropriate solution, now I have three cameras and one is kept apart from the main two.

what was the inappropriate solution?

Eclipse, which is used to clean sensors. From memory alcohol plus gold forms an oxide layer that prevents electricity flowing to the lens to control it.

yea i'd say that's fairly inappropriate.

good for everyone to know that's a no-no
