I bought the hood frame for my L2 from Sports & Vintage Motors - I would expect these could be widened to fit the ND by letting in extra pieces to widen them?
G'day Arthur, Glad to hear you have reached the hood stage with your ND.
I suspect these bows are just wider versions of any triple-m hood frame. If so, they can be easily bent up from D shaped mild steel tube, and that in turn can be made by rolling flat one side of 12mm x 1mm wall round tube.
I can take you through that if you like to email me.
Morning Arthur, Beautiful weather here, for a change! I have attached two photos of the hood frame on my ND which I think are original. They fit and I have had a hood made to fit which looks good and allows plenty of head room, I am 6 ft tall. I can send you more details and photos if required. Delighted to make contact with another ND owner. Malcolm Sorry the photos are upside down - again!
