1960's 727 trans verses 1980's 727 trans

I do not have any trans right now, there was no drive train at all with this 68 Barracuda. It is a bucket seat floor shift car and I was just wondering if MA Chrysler changed the 727's in the 1980's. Will my shifter parts work on a 1984 trans and can I use 1968 cooler lines and is the trans mount still in the same location as the 1968 version? If I do go after this 1984 727 SB trans am I in for any surprises even though it came from a 2 wheel drive pick up truck?
