Well Gents I had not anticipated a rush of demand and I had already dismantled the cardboard pattern. I imagine I can recreate it with measurement from the final form. I am pretty sure it will not fit to a +4 without modification as the wooden one I made for the +4 did not fit into the roadster when I tried it. I think it was the mountings for the shock absorbers that were different. When I have done the test drive to Le Mans I will see if it has functioned as expected. Unfortunately I work away in Norway during the week so do not have much time to get in and do those measurements but as soon as I do I will post some sort of drawing. The idea of a GRP version would I am sure work. I did not have the time or skills to make that work.
Thanks all for the compliments.
If anybody wants to inspect it will be at Le Mans, Metalic Red Roadster V80 ACR.
