Heater box cable questions

Incidentally the nylon pins that are used in the non A/C type heat and defrost controller that the cable ends tie to, mine were so dryrotted i fabricated new ones out of steel drill shank, and machined and pressed on spacers for the space between the levers, and used small locking collars with set screws to hold the cables on. A bit of white lube everything slides like new. The locking collars i will use for the cables at the heater box end instead of those hokey little snap on spring steel washers.
Sweet............This helps. THX
