In your pic above, it appears that the side mounts are attached to the ZF with nuts, although it isn't clear.
If the side mounts are attached to the ZF with nuts, then you can't remove the side mounts, as there is not enough room to slide the side mount off the studs. You will have to bend the tabs.
If the side mounts are attached to the ZF with bolts, then the side mounts can easily be removed from the ZF and chassis without bending the tabs.
