GM part no is... 12558346
Or you can use a rubber freeze plug that expands when you turn the nut. Can't remember the size, but it's just over 1", maybe 1 1/8th or something like that.
I have used a freeze plug and was not happy with how it looked and fit. Got the gm part at the local dealer for $9.
