What is the inside diameter of the rubber trans cooler lines?

I do not have a manual or spec. I wanted to know the inside diameter of the transmission hoses leading to the cooler. My pickup is a 93' with the A518 auto. Any help would be appreciated.

I have a 727 and it has 1/2" lines-hoses. Hose is measured on ID and Lines are measures on OD.

Thanks for the input guys...........I actually called my local Dodge parts department and asked. They had no clue and said they were unable to disclose that kind of info. ????? I ended up calling a local Diesel Hi-performance distributor and they glady told me "1/2" ID. I guess this size was used on 2nd gens as well.
