LT1 T56 Transmission to LA 360 swap

I am doing a challenger tr6060 to an ls t56 magnum.

Here are those input shaft differences
Left is the LS input. Right is the one year 2011 challenger.

the magnum/tr6060 gears are wider and will NOT work in the older t56's

I was also informed that the challenger midplate is at least 3/8 of an inch thicker than the ls midplate inputView attachment 1715834504
Curious, on the TR6060, is the input gear tooth count still 31, or did they change it finally?
