Hardware Dimensions

I have a question that should be simple. I’ve been trying to find out the specific dimensions of the RJ45 jack. I am wanting to stack other boards and I need these dimensions to ensure I design everything properly. It would really help if anyone could give me a specific part number that is used so I can pull up a data sheet for it.

Thanks in advance

Part number is on the BOM.
