Hello, i am from France and i own an US 1981 308 Gtsi, and I was wondering something, perhaps quite stupid, but it's in my mind for a few time so i would be glad to have your opinion about it!!!! I love my 308 Gtsi with his rear quarter fender but, i also love much better the 308 Gtb rear quater window.... I would like to know if someone had already done a conversion to have a gtb window instead of the rear gts fender? whould it be easy to do? would it be easy to go back to origine if needed? And what would you think about this strange idea?.... Ps. sorry for my poor english, i didn't study enought when i was at school, it didn't make probleme to own a 308 but makes probleme to ask something on this fantastic american Ferrari Forum!
