What are the dimension of the post cap? Is it 3.5x3.5 or 4x4?

Will work best with a 4X4 post. Can use smaller diameter if needed. Read information on product description page for further information, there is a picture with detailed measurements.

will this fit the gibraltra large mailbox E1600B00?

The mounting board should fit the Gibraltar Black Post - Mount Mailbox. You will be amazed how much mail and boxes will go in the mailbox!

Will this work for the gibraltar extra large? I have mailbox and black plastic post that came with it?

Check to see if the Gibraltar mounting bracket is wide enough for your large mailbox. The Gibraltar bracket holder is excellent item to use with your mailbox to keep it sturdy,
