I am in the same situation as you. If you want to change the spare tire compartment, you have to cut it out and weld it again. After showing my car to 4S, it means that the spare tire compartment can only be replaced and cannot be repaired. If it's plastic, it's easy to leak when it hits back. The anti-collision steel beam can definitely be replaced and must be replaced. Also, see if the deformed spare tire compartment is against the balance bar below, whether it is bent or not, and whether it is balanced.
