Brake pushrod length ?

Anyone happen to know the lengths of the pushrod for the master cylinders on A body disc cars? I've got one that came with the dart in a box of parts, not sure if its drum or disc and needing to compare to see if it'll work for the disc master I have just put on my polara that is a disc master?

Why not put the pedal a little over half way out , where it is comfortable to you and looks right, and just measure it !!??
