Hopefully you have a Lowes hardware close by. If so go to their =
nut/bolts/screw area. They should also have springs in this area. Look =
for a spring with
the part number of "C 311". It's 1/2" dia and about 11" (?) long. You =
will have to cut the spring to size after you have everything assembled. =
I have not heard about any
temperature sensitive problems and I don't have any, but this maybe =
because it is enclosed in a heat stabilized enclosure.
