Essentially good luck, they are all rather hard to find and this forum is not much help in sourcing rare parts (see the lack of response to my appeals for help in sourcing specific parts).
The front indicators are a rare type used for a specific version of the karmann ghia so try for a VW specialist.
I believe rear lenses are Alfa.
Front logo is fairly complicated, ash tray no idea, header tank is unusually made of brass, light fixture not known.
I'm more than willing to email you good images and measurements of anything meanwhile try in no particular order of listing; ACOC sources as listed in the club mag in particular steve@brooklandsmotorcompany.co.uk, keith@jecks.co.uk (club spares co-ordinator, john spencer (club librarian) for a copy of the original handbook, hawkcars.co.uk (sure I saw some rear lights last time I visited), jonathanbradburn@btopenworld.com.
Hopefully others can help further..
Let us know how you get on.
