AC/Heater control switch cable retainers

I need to make sure if AC and Non-AC cars take different size cable retainers. Inline tube sells a set of 2 different sizes.

 

Can anyone confirm which size the AC cars take?

 

Anyone?

 

My cars are non A/C. I have an underdash box from an AC car here - Will see if any cables are still attached.

 

Thanks Dano!

 

Should be 3/16”. Vintage Air has them and can ordered from Summit Racing.
