In Germany very few Peugeot 103 have been sold with Sachs 505/2 engines as competition from all gear shifted models of Sachs, Zündapp, Puch and Kreidler was big.
I own one of them but currently stored in pieces.
If someone of you guys wants to change his 103 to Sachs engine I could organize needed parts (mainly rear wing).
Just let me know.
