The bodies are the same...
yes, if GS spyder to spyder, GS to coupe.
not sure if buzz read your question carefully.
so, if your question is asking if the (Spyder) GS's 'surfboards will fit on to a 2002 Spyder, then very likely yes.
What about them (Spyder GS's 'surfboards) fitting a 2002 Coupe? no.
The coupe has a wheelbase 8.6" longer than the spyder.
if you want to fit them on your 02 spyder, you need one from a GS spyder.
