V65 SP inner fairing

hi is it me or am I missing something, no really ! I have a V65 SP 1984 with a oblong headlight that looks to small for the fairing aperture although standard for USA the glass is totally flat fronted opposed to what I have seen on other Guzzi’s are the headlights interchangeable for different markets ? 7 if so do I need all off the frame work for that headlight type ? lastly the parts book shows some type of inner fairing but the parts book is so faint I can not identify the part no or shapes or better still if a member has any for sale would be great. any help here would be gratefully received. I will be away from my computer for two weeks so I will be unable to answer any replies before then thanks Dave.
