I have a 1966 shell valley with a 289/ 4 speed top loader. About every 6 months the pull slave servo arm brakes off where the arm passes through the chluch fork. I have made the hole larger and a thin layer of teflon grease on the rounded locking bolt. The alignment looks good with no side loads or binding.
Does any one have any tips. I just replaced with a new one.

Thank you for your help.
