Yes its been posted a couple of times. It goes like this:
Transfer case rebuild
Its not the adding of plates.
Its the arrangement of them
There are 19 plates in the standard setup, 12 outers and 7 inners to make up the clutch pack,
Outer = O, Inner = I when reading the layout below.....
Stock is IOOIOOIOOIOOIOOIOOI
Full max grip rearrangement would be IOIOIOIOIOIOIOIOIOI
You only need another old transfer case to rip the plates out of to rearrange your old setup, scavanging the extra inner plates to use, you need to select ones of the right thickness to end up with the correct end clutch pack thickness so some mix and matching is required.
You don't need to go full grip, you can make up your own arrangement of plates like something in the middle like IOIOOIOOIOOIOOIOIOI
Same theory as playing with a Cusco LSD clutch pack arrangement, see page 9 below.......
