For sale is a used-one time tool set to replace the #5 Dzus fasteners on the early style Bonanza/Debonair (perhaps others?) engine cowlings. I bought this brand new in July from Aircraft Tool Supply (
https://www.aircraft-tool.com/shop/detail.aspx?id=MS-ZC) to replace mine, used it (worked great!) and then put it away. I was cleaning my hangar today and discovered another complete set of these tools (

), so apparently I now have two!
My loss is your gain. New I paid about $70 for the unit, so I will let this go to a lucky new owner for $50 shipped. There are lots of other dies available the work with this clamp for different Dzus requirements, but the die set I'm offering is only for the cowls (or any other #5 Dzus fastener you need to replace). Each die set is about $43 from ATS.
