cylinder block drain plug size?

[Bubbabgd7@aol.com]

Hi,

  Anyone know the cylinder block drain plug size for a '93 SE-R and care to
share it with me? I called up the $tealership and the parts guy said his book
dindn't show any cylinder block drain plug.   The drain plug was a bear to
remove, and now only wants to thread easily about half-way. I found a couple
of little flat spots on the drain plug thread so I was thinking a new drain
plug might help. Please respond directly (or also to the list) as I am on the
digest.  And yes, I checked the archives. Thanks.
