Can you repair an iPhone 5S with an iPhone 5 screen?

I have an iPhone 5 digitizer / LCD assembly and I was wondering if I could fit it onto a 5S. Would it also fix the 5C? I'm not sure as to the differences in the parts.

Yes and No, The old iphone 5 screen has the exact size for the 5c. But, the iphone 5S has some tricky part where the fingerprint sensor is placed. Unless you know, you could repair the 5c screen with a 5 version.

No you can't.
