Transmssion Interchange?

Don't know about the case, and not completely sure, but I think you need to change out the clutch also. (Splines vs tapered shaft?). Also starter gear tooth count will probably be different so that starter gear will need to be changed at least. Might even need the later starter.
I would look at some of the online parts diagrams and compare part numbers.
The easiest way to do this is remove the shafts from the Dyna trap door, and transfer them over to the Softail trap door.
The reason for this is because the Softail trap door already has a drain plug.
If you were to use the Dyna trap door, you would have to drill a hole for a transmission drain plug.
You would also need to replace the clutch, because the `95 transmission has a splined mainshaft.
An OEM clutch 1990-1993 will be a direct fit.
A later clutch will work but will have different starter ring gear tooth count (requiring a different starter pinion gear)
A later clutch will also have a different primary chain sprocket tooth count.
Note: The process of removing the shafts from the trap door will damage the trap door bearings, so they must be replaced.
