Ford sos to 4 speed

[OneDayItllRun]

I'm trying to swap the rear end of an 891 with sos tranny onto my 4140 with a 4 speed. My question is about the drive shaft swap. If I remove the outer seal going into the differential will that allow me to pull the drive shaft or am I going to have to disassemble the entire rear end?

The drive coupler comes out when you separate the transmission from the axle

Thanks. I just had to pull a bit harder
