There is a saying "you can never have too many clamps" and even with all mine you can come up short sometimes. Infact at that size I would have popped it in a vacuum bag which does a great job of things like that but you have got to use what you have.
I remember an article in Smithsonian air & space I think it was about an Australian airline flew to London and such. They would strap extra engines on outside the plane that they often needed later in the flight rather than a spare later down the road. Scary time to fly if you ask me.
