After a lot of days with short time, I finally had some time last sunday to work on my car.
We started with making an airscoop for the enginelid. TO first have an cleaned lid, we welded some holes closed, and cut out al the represt pieces, maked some new plates and welded them in. After that the hammering begun to make the sides of the airscoop. They're both finished and one already welded on the lid=> see the pictures.

Also are the holes were originally the heating-tubes are mounted welded close.
