555,
Back when I got my 2000 Boxster S I knew I would want a hard top to go with it to give it a more vintage look which I like. Months after looking I did find a second hand one that matched the same Artic Silver from my 986 S. The shop helped me install the top and after a while I did notice that it was a bit noisy and the fitment when removing and installing was a bit sloppy? I went to the dealership and found out that there is a Hard Top kit that must be purchased in order to maximize the fitment of the top. It's basically 2 cylindrical stub shafts with a key notch that need to be applied into the holes on l & r side where the handles tighen down on. They are keep in place with an allen head type screw. If you got your hardtop second had you don't have this on your car as it's only requried for hardtops.
