Late 987.2 Convertible top transmission swap to a 986?

[papasmurf]

I was able to source what I think is a pair of good transmissions from an '10 boxster and all the associated equipment (cables, lifting arms, tonneau shocks) apart from the motor and the mounting pins for the body. I have done some google research and some people say there is a transmission upgrade but I was not sure whether they were referring to the later 987 setup or some kind of upgraded 986 specific parts. From what I gathered it may be possible to swap the two but I read somewhere that you need the mounting pins that connect the transmission to the body as they are different or upgraded? Is there anything else I am needing? I rebuilt my transmission gears last year but never could get it synced correctly with the top (ball pivots kept popping off even after replacement). If this is a relatively simple swap I may give it a try and sell my spare 986 stuff.
