Yes (we've had it happen to us), although the stretch you are trying to do is not as popular as Pumphouse to Rancho. Most campsites are big enough for one group. I have heard of groups getting upset in the past when other groups have tried to share camps on this stretch, which you shouldn't have to do. Approach with caution of you decide to try this. Print the map, take a GPS, and be aware of where you are on the river and you'll be able to find the designated campsites. I don't remember there being signs with the names on them. Being flexible is the name of the game on the Upper C. Don't forget your earplugs, as the railroad is right there. Also, not sure which weekend you're thinking of, but there is a big show at State Bridge this weekend, so the lower stretch of the river might be busier than normal.
It's nice that the "lower" Upper C is not as popular as the Pumphouse to Rancho stretch...yet. That might be why the answers here are sort of vague, no one wants to give out the campsite info. That being said, they're on the map and have been mentioned here previously. Take the GPS (or watch the topography) and follow the map and you'll find them. You can also call the BLM office and talk to a ranger for more detailed campsite info/private property info to be sure.
