I still have the scars from working on Spey Mk 202/203's. The aircraft was designed for a GE powerplant that slid in beautifully on a rail. The Phantom Spey however was larger in diameter, & hence went in on a special installation stand, that inched forward then up an inch etc, until you could get the mounts attached - once installed changing LRU's was an elbow bruising exercise, usually associated with an armpit full of JP4. As for ground runs, it was the only aircraft that I ever had to wear a leather body belt when setting up the reheat (afterburner), this was a precaution incase of reheat buzz.. ah happy days;)
