[_paralyzed_]

To expand on what BlazerSS wrote, you can make a newer tranny fit an older flm chassis with an adapter plate flm use to make. Actually, the newer tranny would fit almost any older chassis with the adapter plate flm used to make.

It is not a direct bolt in fit.

FLM doesn't show the plate on their website, but you may still be able to acquire one if you contact them.
