You could try this siteCarfiche There is a full set of microfiche for C4. The site also has them for C1 to C3 also. It takes a little getting used to, but it is good for finding parts and diagrams. Good luck.
Ihave the view you suggested but it is not for a 1994 year. It shows the earlier bumper style. This might be the same except for the cover but I'm not sure they haven't changed a few things, do you know the code for the later bumper?
