ok so im nearly done building my B17, when i realized that i dont have the freeze plug. I go to Honda to pick one up but they tell me they never carried any and i wont be able to buy one, so i was wondering what to do about that, is there some where else i can get one with out having to salvage one off a junk yard motor or something? Thanks for all the help

 

Measure the diameter, call up a napa or other auto parts store and ask if they carry that size.
