904 to 727?

I'm interested in replies from those that have made the 904 to 727 swap, while retaining the column shift.

Are the column shifter linkages down low on the 904 different from the factory 727 linkage?

What about kickdown linkages between the 904 and the 727?

I have a 340 and a 904/column shift in a '71 Duster; I also have a rebuilt SB 727 that I'd like to swap in.

I know that the driveshaft has to be shortened when swapping to a SB727.

Any help is appreciated.
