CUCV head leaking coolant fluid

[Draco-87]

Ok guys (and gals) got a coolant leak from the passenger side head. It looks to be comming from below the pass. side front intake runner. and it looks to be a very small freeze plug? i have searched the internet (no joy) and gone to the parts stores and no one has seen or heard of a freeze plug this small. Question is is this a freeze plug? and has any one had this problem before!

Thanks for posting the number.

For everyones future reference, the TMs provide a wealth of information.

Looking at the TM 9-2320-289-34P parts manual, Figure #2, is where the quoted part number is found.

Googling the number show various parts houses have it.
