A727 DipStick length?

Well, I called Hughe's transmission tech., (which I should have done first) and the tech. guy said, "the fluid should be level with the top of the trans. pan, cold". He stated, " start the car in cold in natural" and check it. He also said that this level would put it between 1/2" and 1.000" below the dipstick hole. So, all I need to know now is the distance from the bottom of the dipstick hole to the top of the pan. I'll have to jack the car up in order to measure it, unless someone has a transmission out and could tell me.
