I would probably order from Monoprice if you have a choice.

But here are some suggestions. I didn't do much of any research but this is basically what you need:

• Keystone jacks: https://www.amazon.com/Cable-Matters-Listed-10-Pack-Keystone/dp/B00IO3HEN6 (or a different version if you have cat6 cable)
• Punchdown tool: https://www.amazon.com/TRENDnet-Storage-Interchangeable-Reversible-TC-PDT/dp/B0000AZK4D
• Wire stripper/punchdown tool (if you're only doing a couple this should be OK): https://www.amazon.com/VANICE-Stripper-Network-Telephone-Computer/dp/B08LT8Q23G
• Some sort of keystone patch panel that mounts where you want it (there may be a version specific for your enclosure if you have one): https://www.amazon.com/Leviton-47689-QP-QuickPort-Multimedia-2-375-Inch/dp/B000LENCR8 or https://www.amazon.com/ICC-Blank-Mount-Zero-U-IC107BP12V/dp/B001UKAW16

You could use a keystone style patch panel with RJ45 coupler/passthrough keystones similar to this. I would recommend against this but it is probably the option your looking for.

If you want one that is in the style of a 66 Block you can buy this and supply your own rj45 coupler keystones from here
