For the original bolts on the cross member hammer on a 3/8" socket, they're so soft it'll go on easy and a 10mm socket will probably just spin. Use a breaker bar, nip it up and then back it off, they'll either come undone or shear off. If they do shear get an 8MM drift on the sheared end and hit it up hard. The captive nuts are only tacked on and will pop off very easily. Did all eight of mine in 30 mins, 6 undid and 2 sheared.
