Many thanks 9FF
Of course You are right about this! I sent them an e-mail and I hope!
The owner of the GT visited Freisinger Motorsport as they has/or at least had a lot of parts for these cars. They didn't have the parts he needed...
I have asked Edmund Harris in England, TRE Motorsport in the USA, and now the Almeras brothers in France if they know anything. Almeras used to Rally several of these cars, so I may get some information of pictures from them. I really hope so!
Again, many Thanks!
