floor shift/console bracket locations

That’s how I did it on one of my cars. I left the top plates off when I was positioning it.
someone said that at 1 time there was a diagram posted, with dimensions, to install the floor shift and console brackets when changing to a floor shifter from a column shift. i could not seem to find it. would it be possible to locate the pivot that goes thru the tunnel 1st and then back track from there? tia. rick w.
