okay its not all that hard to do.. i have an ap1 MY01 or 2001 model S and i did both taillight and headlight conversions to an AP2 or 04-05 S model....the difference in the taillights is the mounting bracket is to big u have to drill the holes or grind it down bigger to fit the new taillights but they fit pretty flush also for the headlights u dont have to change the bumper or anything just for headlights you can if you want but the ap2 headlights will fit an ap1 s with out any modification to the body or frame.. the only thing you really have to modify is the new ap2 headlight housing underneath where the brackets are... if you want detailed instructions with pictures join www.s2ki.com im on there as "s2k jimbo" you can pm me on there if yoiu have any questions or comments...

you can check out www.hardtopguy.com for a retrofit kit for the headlights its about $700-$800 so if u sell urs for a few hundred it wont seem as much.

heres a picture of my S...
