I’m putting a gate in this space and need the latch post to go on that stucco wall to the right. The only issue is it’s stucco, then cinder block so a lag bolt won’t work.

I’m hesitant to use triple grips or something similar because of tear out. Any ideas for securing a 4x4 post to it? It will sit on a concrete sidewalk so I could use a post base but that’s if there are no other options.

TIA!

And yes I know the fence is a bit crooked, had to avoid a huge root.
