Can anyone tell me the thread size for the oil drain plug? HD Gas

M12x1.75x12mm
Thank you. I ordered a valvomax drain oil plug. I have always been against those things but finally got one for my newer Jeep that requires 6 month oil changes regardless of miles.

But, then I slid under the AT4 and saw how the drain plug already hangs down a bit. The drain plug and filter are probably the easiest to get to of any vehicle I have ever owned. Driveway oil changes are going to be a breeze. I canceled valvomax drain plug valve. They are a nice design and I did some testing on the Jeep to ensure it does not go up into the oil pan and prevent the last bit of oil from draining just dont want it on the truck.
 

I've had a Fumoto valve on my HD for quite some time and haven't had any issues driving over all sorts of terrain. It's got a nipple on it so I hook the hose up before opening the valve and don't have a mess from draining the oil pan. If interested, I've included a link below.
