Since actuator removal is a P.I.A. even with bolts instead of the roll pins, I didn't want to have the jamming problem again. The general feeling being that adapting a modern replacement was a waste, did the next best and added a limit switch to prevent the motor driving into the end.
A bracket for a microswitch that utilizes an existing motor mount bolt and casting configuration to locate and attach to actuator. Aside from removing actuator, hardest part was finding a proper 5/16" wide terminal so as not to mess up existing motor connector. No Packards were harmed and all is plug in and easily removable.
Because of the intertia, switch was adjusted to cut the power slightly before the end of travel. Nothing apparent to jam so doesn't seem to be a need for anything at the other end.
