During this year's inspection the PR flexible shaft seems more difficult to re-install than previous. Is there a good trick at easily aligning both square cable ends with the power drive sockets?
 
Attach outer cable sheath to bendix without the shaft inserted.

Next insert flex shaft. Hold the flex shaft from falling out of the sheath as you insert it into lower drive unit. At this point the flex shaft has come out of the top socket. The bottom of the sheath is still not attached. Hold the sheath away as you align and insert the flex shaft.

Last align and fit the sheath to the bottom unit keep turning the rubber prerotor wheel till the top cable end aligns with the square socket.

Tighten everything up and safer wire. You should be ready to go.
 
Worked great GC! Thank you. I think a fresh day and fresh cup of coffee helped too.

How clever! The Bendix holds the (upper) sheath, whilst the the PTO drive socket retains the (lower) shaft. Then, pop the shaft in the Bendix socket during the turning of the prerotator drive wheel. Really ingenious. Do take a bow for that!
