The brass connectors were found at a great local store called Rural King.
If you don't have a Rural King in your neighborhood, you don't get to enjoy their complimentary coffee and popcorn,
and a pleasant helpful customer service,
and a wide variety of assorted merchandise and equipment
(and the such).
for hardware like nuts and bolts,
DO bother to compare their prices with the big box stores!
They don't charge per nut or bolt.
Rural King sells
by the flipping pound!
Suffice to say, the community here in Springfield loves their Rural King
