where to weld Z-bar bracket E-body

I am converting my 71 Cuda' to a 4 spd. Where does the Z-bar bracket get welded on the frame rail? I need specific measurements, and a pic would be nice too! Thanks

There is a notch in the frame rail. Line up with the access hole that's in your inner fender well

Thanks- I should have noticed that- sometimes easier to just ask-
