Thanks to Sid for the article. The corrugated plastic sheet arrived today and I have found a supplier for Stainless bolts, nuts, washers and 3mm * 30cm * 1m stainless plate, I have ordered these and should come next week. As Rosie is a Plus 8 the wings are wider than the Wells ones and fitting may be slightly different, so I will document the measurements for the inner wings and brackets as made, and any issues I find and post for others.
