I suspect I'd need a 3mm left hand die...in hopes that it would clean up the threads. That's my best guess as of now.

Yep, 300 front and 1200 rear. No spillage and the rears only filled up about half way. I don't recall how much was in the bottles specifically, but they were no where near full. I had to use every drop from each bottle. Fortunately, the front was mostly full, but it was marginal. I had to add my own oil to fill the rears.
