I am reading your post with great interest.
I have a couple of questions my self.
1.the "Gasklep".. what is this?

2. Do you know of someone or somwhere (like a garage or MGF-freak) who can help in the mounting of the Galsklep?
3. I see you have the Viper on your car, did you put it in your self, and if so, is it hard?
Thanks for great info so far!
Best regards,
Jørgen
