I have a TLS on my A10. To set it up first disconnect the link rod between the two actuation levers. Pull both levers into the "on" position by hand. Now, is the link rod still the correct length? If not, adjust it so it is and refit. Now when one actuation lever is pulled into the "on" position, both shoes are contacting the drum together.
Now, fit your cable, beware there are two types of TLS backplate, one has the cable dropping down the leg and the other has the cable coming in horizontally, I would guess the later has a longer cable.
There is nothing special about this, its the same STD set up whether its fitted on a 58 A10 or a 65 Bonnie or an A65. The only thing that would affect the set up is if the linings were worn out.
