I picked mine up at a napa for $25 +/-   it's a 1 1/4" diam freeze plug.

I don't know the part number, and you may have to plead with them for
abetter price, Napa often has a price line for their 'independant' small
garages and it'll save you a few bux.
it's worth the time to finnangle a 2nd price line with them, if they
think they'll see you more often then they'll be more likely. also all
in all they've generally had what I've needed.. I prefer them over
new_china_imports... err popboys these days.
