I spoke with my contact at Toledo and he informed me that the Toledo Master Cylinder # 10614 that you referenced has a distance of 3-1/2 inches between the mounting holes.
For a replacement metal shaft and return spring assembly you will want a Replacement Push Rod Kit # 34850590. view full answer...
What you will need is the Dico Replacement Shock for Model 6 Actuators, part # T1242600. This part is for a Model 6 brake actuator like the one in your trailer.
The bolt holes of the Replacement Shock Absorber for Toledo Brake Actuators, part # 1844-2, you referenced measure 7/16 of an inch. Also, this shock is not designed to be used with a model 6 brake actuator like the one in your Teenee trailer.
