Thanks for the replies Frank, the pics and text are a massive help tbh. I should have enough info and inspiration to build something half decent, following your lead 
So I think what ill do is go and find a throttle body today/tomorrow and ill try and get the matching inlet manifold. If not ill just study it and take pics.
Ill most probably attempt to make an adaptor plate to mount the a new throttle body onto a cg/cga inlet.
I made an adaptor plate to mount the throttle body on my driftcar so should be to much trouble,
Can you see any reasons why I shouldn't make an adaptor plate?
