Help taking my broken electric roof off SORTED

Trying to take my broken electric roof off my j reg clipper to replace it got everything disconnected all apart from the hydraulic rams. Can any one tell me now to disconect the top of the rams from the roof frame I was expecting a cir clip but it looks like a pressed bolt.  Any help appreciated

Managed to find the smallest cir clips in the world roof is off just waiting for replacement to arrive
