For the typical SF situation, you also need a centering ring to locate the bell housing to the absorber.
The Mopar bell housing also puts the engine farther forward, and has the crank farther away from the input shaft.
In order to get the pilot of the shaft centered on the crank, you either need a longer than “standard” shaft, a spacer behind the shaft to move it closer to the crank, or an extension located at the back of the crank....... the latter of which is what we do here.

The bellhousing gets drilled to facilitate two of the lower absorber mounting holes, and we use bolts with nuts to secure it.
We bought the correct centering ring from SF to locate the bellhousing.

None of it is hard........ but someone has to “want” to make it happen.
