I did fetch one back from Vinh Long to Bien Hoa arriving late one evening....having experienced a bolt failure on the four point lifting device provided by Cessna.....was told it was the same as used for the O1E Bird Dog.
Interesting days those were.
I learned I was not bullet proof but was protected by lots of good luck and a Guardian Angel who earned his Hazardous Duty pay and an excuse for his excessive consumption of strong drink.
Odd....most of us always thought it was the other guy that had the bad job.
