Hey chaps....
It can be done (eventually!!) and work on my 1303s 1975 German looker has just been completed and shes been set up like a dream on the rolling road!!!
has been a hard slog for many people but wanted to send a message to those engaged in this conversion... do not give up if its pissing you off COS ITs IS WELL AND TRULY WORTH IT!!!!!!! I CANT STRESS ENOUGH HOW MUCH BETTER I HAVE FOUND IT IN TERMS OF raw power + fuel economy and reliability!! and you can get a decent heating system too...
here is the lil beast...
and one with the lump visible..
