Mine is more radiused, less sharp-angled than Mr Morris's, but I think he got that wrong. The radiuses on mine are similar to the ones edging the windscreen. Also, I used thicker material, so I think it ought to add strength. I have decided that I like it so much I am making one for the other side, even though that one is in ok condition.
Will weld it in next weekend. Will also then fit starter motor and coil.
