Moving an Evo Dyna Driveline into rigid frame

Do we need to swap the rubber mount Dyna for a softail transmission to make the 5speed work In a v-twin 51-1948 frame

I have an opinion. Was told by someone with a phone my opinion was not important. They knew.


Is there a tranny plate for a 1995 Dyna 5speed to mount in a 4 speed rigid frame?
