Thought I would follow up in case someone else has this issue in the future. The valve cores are 8mm and 10mm. They are referred to as Eaton Schrader valves. So if you ever want to change out valve cores without losing freon the correct tool to get is an Eaton valve core removal tool. Mastercool sales one. They are expensive, but they may save you money on a complete recovery, vacuum and refill job.
