ox with some kind of reinforcement bar?

i am cutting a hole in a brick wall to put in a through the wall mailbox.
The wall supports a brick pillar holding an iron gate.
The pillar will not be able to support the weight of the gate once disconnected from the support of the wall.
Is there a way to tie the pillar to the wall over the top of the new mailbox with some sort of reinforcement bar?

"You put the nail box higher than the top of the gate so the pier stays strong, Then depending on size take down the top of the pier and rebuild you can use skate as a bridge on the opening,"

"Think with out seeing it use plates to bolt both items together bars I feel won't be strong enough if the pillar is open fill with concrete then insert bars but plates bolted both sides seems a plan"

"From your description, it sounds as though the brick pillar is relying on the adjoining wall for lateral support. If you cut a large opening for a through-the-wall mailbox without providing suitable structural support, there is a risk that the pillar could become unstable, particularly with the additional weight and movement from the iron gate.
Although there are methods of tying masonry together using stainless steel reinforcement bars, helical bars or proprietary wall restraint systems, the correct solution depends on how the pillar and wall were originally constructed. There isn't a single reinforcement bar that can simply be fitted in every situation, and installing the wrong type of support could compromise the stability of both the wall and the gate.
Before cutting the opening, I would recommend having the wall inspected by an experienced builder or structural specialist who can determine whether additional support, such as reinforced masonry, steel restraint, or a suitable lintel arrangement, is required. This is particularly important where the wall carries structural loads or supports heavy gates.
If the pillar becomes unstable, it could lead to cracking, movement or even failure of the gate support over time. Spending a little time ensuring the correct reinforcement is installed before making the opening is far more cost-effective than having to rebuild the pillar or repair structural damage later.
Whenever structural alterations are being made to a load-bearing wall or one that provides support to another structure, safety should always come first. A professional assessment will ensure the work is carried out correctly and that the finished installation remains both secure and durable for many years."
