What size are the nuts that secure DD3 Chamber?

[ChuckMC8]

I'm trying to help with roadside assist- (7:00 am Friday 7/16/2010) 102C3-the nuts that hold one of the DD3 chambers to the bus are gone- anyone know what size and thread these are? IIRC, there are two nuts. Does a 15/16" wrench fit the nuts? It will help these guys get the hardware if I can specifically identify the size. they are 20 minutes from a hardware store- thanks, Chuck

In a word, Yes. That's what was on mine.

I have an old dd3 can that I measured.  The studs look like 5/8 sae thread .
I hope that helps.
