Question:i need a 1 gallon mason jar. or some other simple 1 gallon glass jar. i cant seem to find any in my local hardware stores (they only have 1/2 gallon) and ebay was no help either.

Answers:
I don't think you can buy a gallon mason jar since it's totally impractical for home canning.

However, if you like dill pickles, grocery warehouses and restaurant supply stores still sell dills in a dandy one gallon glass jar with a screw top lid.
