Well, I got one window out with a little daylight left, and broke the plastic pieces. I have the same ones, though. I'll try to be more careful, but the plastic is old and a bit brittle.
I'll get you at least a couple, bubble wrap them and mail them out by friday. They should be there next week, provided I don't break them. Three were already broke when I got the bus, so I'll do my best.
I did spill a beer messing with this widow today!!
I wish they'd just made them of metal.
Only my emergency windows have these, the others have the pot metal wedge shaped ones mounted to the windows at the corners.
It you're handy, I think these could be made from wood if done right. It wouldn't be too hard really.
Just a thought.
