brake line fitting size HELP required please

[nismobrown]

i am fitting a Wilwood prop valve to my 97 gts and need to connect it to the lower brake line ,the largest one closest to the windscreen that comes up from the chassis from the rear of the car.

please can anyone confirm the exact size of the fitting at the end of this pipe that screws into the stock dodge valve .

thanks!

Are you concerned that the prop valve and the line are different thus you are looking to buy an adapter?

yes, i was after an adapter to connect the willwood smaller threaded hole to the larger 97 gts rear brake line.
i think i have one sorted but will not be 100% sure until it arrives.
do you know the exact size fitting required ?

thanks!
