Here is a red 987 gt3 bar (TPC i think) on top of my old Tarett 986 GT3 front bar. Except for being slightly wider and the different collar locations, it is the same. I didn't try moving the 986 Tarett to my Cayman (maybe the Cayman needs that extra little wodth) but i doubt that extra width from the 987 bar would hurt going onto the 986, since it has adjustable shaft collars.
