C4 to Adapter Gasket Replacement

[70HalfCab]

The gasket between the back of my C4 and the adapter housing is leaking really bad. It has been a long time since I’ve had this apart so just need a bit of guidance. If I unbolt the adapter housing from the back of the C4 and of course remove the cross member, drive shafts and linkage can I leave the adapter attached to the transfer case and slide them back/off as an assembly to change the gasket? Any tips on reassembly to make sure it is leak free?

You can do that but it is very heavy and awkward with the TC clocked the way it is. If you can secure in position on a jack, that might help.
