Herb,
I apologize but unfortunately I do not have much for you to go on. I checked both the work order and log books and both entries say the same thing. "Trim actuator hardware loose. Secured all trim actuator hardware." Total labor 0.3 hours. The records indicate that nothing was replaced but simply secured. Sorry, I wish I could be more helpful. Ed

No worries Ed
I looked into some parts and they are expensive. I will try to rebuild without having to buy new if possible.

The service manual may be helplul, e.g. the 1965 THRU 1973 SERVICE MANUAL Sect. 8-3 ELEVATOR - TROUBLE SHOOTING table pg. 8-3 has two suggestions to address "SLIGHT UNDULATION OF TAIL DURING FLIGHT".

I solved my boom bounce by adding a bit more torque to the elevator hinge bolts. I had to go beyond the recommended value. My IA didn't want the compression on the bearings but in the end the smooth stable flight characteristics were persuasive. Check for even the slightest play and eliminate it. If you can't find anything try a bit more torque on those hinge bolts a bit at a time.
Best of luck _travis
