[TowerTalk] Aluminium wanted

[r miles]

I am in need of a  peice of 1/8'' aluminium plate apx 12'' square. It's for my 30m Moxon I'm building. Antenna is assembled & ready to tune. I want to stiffen the element truss supports.
I've tried the local hardwares & Lowes. Living in a rural small town has disadvantages sometimes. I looked on EB but nothing thinner than 1/4''. I think I would even  settle  for steel or aluminium diamond plate.  Just  want to keep the weight down.
If you have one to sell or know of a source please contact me off reflector.
