Ac Superblower/Mk4 Front Inner Wings

[Superarnie Mk2]

Dear all,can anyone tell me if there is a difference in profile between the front inner wings of the Superblower and Mk4 cars. I wondered if, due to the location of the superchargers was the profile altered on the Superblower. If any one could post images of the inner wings (feeders?) we should be able to compare. Also has anybody got rid of their grp inner wings and converted to the aluminum panelled inner wings, I would be very interested to see how you did it.
   Many thanks in anticipation of your help.
