Cleaning and Replacing Windows

[CO_Skymaster]

The small springs to my foul weather window have broken, so the vent window just swings closed. I tried to have my A&P replace the springs, but he said Cessna didn't have these. I would like to have them replace at my annual this month. Has anyone else had to replace these and where did you get them. I've looked on Wicks aircraft and the aircraft spruce websites and can't find them there either.
