We bought some at the last CC rally we attended. CC parts has them in stock. As I recall they were pretty cheap, but I'm not sure of the actual price ... maybe $0.75?) Anyway, the CC tech folk told me a trick.

When you install the replacement, be sure you add a drop of silicone caulking compound (clear) to one of the clips (NOT BOTH... you'll seal up the weep hole!).... but adding a dollup of clear sealant acts as a glue to keep the clips in place. (They tend to come out when the windows get pressure washed...)

Thanks for the tip.

Last week I called CC and they are only $0.49 each so I ordered a dozen for each side since shipping is the real cost.

I'll try that trick with the caulking.
