Will this fit 6400p-r-10 mailbox? 11.3 x 18.2? (It's recommended by Architectural Mailboxes, but doesn't look like it will fit.

The post and hole in the adapter plate are 3.5 x 3.5. I cannot get it onto the post. Advice?

Hello, we are sorry to hear that the adapter plate will not easily slide onto your post. We suggest sanding down the top edge of the post so that the adapter plate is able to fit onto the top of the post. Thanks for reaching out!
