They will have what you need. Call them.
I will do that... Thanks for the suggestion.
Well... I emailed bowmans stove and no dice. They told me that this was not a common part and they would have to get one from the foundry where ever that is and it won't be available until after the new year.
So, what I did was to take a 6" long 3/8" bolt, bent it 90 deg about half way, grind off the head. then I stuck the bolt under the latch hook and made a cross bar and screwed a nut on the end.
It's not elegant but it works. I'm thinking of having a new latch made out of 3/8" steel.
