Jimmy Mac,
Thanks for posting the MkIII side window. I have never seen a real MkIII in person, and from the looks of it, a possibility exists the set-up could be made to be able to remove the larger square portion of the window? I do
not know for sure. Maybe someone that has more first hand knowledge could chime in on this one. Anyone out there that works in a race car shop that has been close enough to expand on this?
Thanks again for posting the picture. Me being an old fart, I tried several times to post the thing, and failed.

When I have my son over to the house for dinner the next time, I am sure he can guide me in the right direction.
One last thing.....do you know of the chassis number of the car in the picture?
Thanks,
