Sometimes, rotated units fall into the dreaded overcammed category. Overcammed means you can't retract the cables any farther and the cams are working like nuts. The unit slid in initially, so your task is to find that path. Try to move the unit into a wider spot. OK, here is the big tuna, the trick that has gotten me more cams than Sly Stallone can carry.
All cams have an axle.
Often a little tap or yank in the direction of the axle will budge the sucker enough to move freely. Sometimes you can slide the unit sideways all the way out of a deep walk-in, never touching the sling or triggers, and bring home a beauty. Violence rarely works and may turn a good find into crack litter. If the cables are broken try moving the cams one at a time with the chock tool. Call me and tell me where it is.
