<VV> another diff interchange question

[Ramon Rodriguez III]

I imagine it is easy to swap internals between a diff for an automatic and
a diff for a manual trans?  I ask because I currently have a line on a POSI
diff that is for an early 4-speed.  My winter car is the 63 PG car and I'd
love to put the posi in it.  Can I just take the internals out of the posi
and install them in the PG housing?
