I bought 2 of that same part number from Hill Aircraft 2 years ago. Did you ask, or did you assume from the internet price list that they wouldn't break a pack? The internet listing is the way they are supplied to the dealer, but something like this that is replaced fairly often is kept in stock at most dealers, and can be sold individually! If they won't help you, contact
Spectrum Aviation [
spectrumaviation.org] (Cessna dealer) in Lexington, Kentucky! They've always bent over backwards, for me!
