Floor shift linkage hodgepodge
I have 2 different torque shafts but I can’t find any info saying the one in the car wouldn’t work with a 727.
Console shifter with 904 linkage to a 727
Lower Shifter Bracket : suit 904/727 Torqueflite Selector Bar
I can tell you that I swapped my 727 out for a 904 in my 69 dart.
All the linkage stayed the same the only thing I had to do was have a new drive shaft made 4" longer.
Now that was with a Lokar kick down set up.
I do think there is some difference in the factory kick down between the two.
(Lever.)
Since then I put in a Quicksilver cable shifter with a reverse pattern manual valve body so no more kick down stuff to deal with.
I like it so much better.
Hope this helps..
