I am still a newbie to this forum so I apologize ahead of time for asking questions that may be understood as stupid, I am doing my research but have not acquired every shred of information yet, although I am working on it . My question is about fuel tank material by year, when did norton switch to using steel tanks? I recently picked up a 1973 750 basket case I am planning on reviving it as a roadster. I got a steel tank with it that looks like someone tried to smooth out the seams and failed in their attempt to improve on the looks. I have not decided if i want to restore as close to original as possible or make it my own with modern touches. I have a lead on a fiberglass tank and side covers with fresh paint and sealed with caswell. Before I make a decision on buying them or not I would be very interested to know what a 1973 roadster came with originally for a fuel tank. Thank you fit any help anyone may be able to provide.
