I believe that comes out of the big Chrysler engine book. I have three of them and I know it’s in the two early ones. The earliest I have is 1979 and I try and not fiddle with it much because I wore that thing out.
The other one is from the mid 1980’s IIRC and I had to put that one into a 3 ring binder to keep it together.
The newest one I have is the last one published that I know of.
I know it’s in the first two, probably in the manual transmission section of the book.
