Need picture of 64 Val heater box

Pictures are of my 64 Valiant heater box. I cleaned and rebuilt it but one of the control cable brackets is missing. I believe that it is for the temp control door. The shaft is between the heater core copper tubes. No clue why or how it got broken in the possession of the previous owner but I patched the busted out section using JB Weld reinforced with fiber glass mesh. For some reason the diagrams in the 64 Valiant FSM do not match the actual box that came out of my car.

Can someone please take a picture of a 64 box so I can see exactly what I need to add? The location is marked with an arrow on the blue tape. I have 68 and 69 heater boxes I can use for parts.
Thanks!
