[DeTomaso] Crane Link Bar Lifter Failure - Pictures

[John Taphorn]

Orville

While it was disappointing the day of testing was cut short and the engine 
did not return with you, the alternative of finding out after installation 
in the Pantera would have been emotionally devastating at this point.

I'm confident things will work themselves out just fine in the end.
