[29Cabriolet]

I too was a victim of this tank damage due to the steering wheel mount. I did not want to remove the tank either. But in response to some advice (even some scoldings to "do it right" from this forum) I did. It was not an easy task but in the long run beneficial. In the process, since the firewall is part of the tank I replaced all the ignition wiring as well. For the tank I removed the riveted mount and TIG welded the the rivet holes. Then had the inside coated by a radiator shop. Repainted the entire tank with a rattle can. Color is one slight shade lighter but un-noticeable. 3 years later, not a drop leaking.
