cam chain guide question

[sbaugz]

I removed my cam chain guide to inspect. Pictures are below. The plastic part that actually serves as the chain guide looks perfect and there is plenty left but the side rail sections have cracked. I would assume I have to replace this?

I would replace that guide for sure
