Hi Mark, Thanks for the reply. I'm really after an old plastic one to copy as I understood they were an odd shape, so the measurements were to give me an idea of materiel requirements before I start. The top of my dash is out, as is all the ventilation stuff, wiper mech, radio and some wiring too! So I have a larger space than in reality, and was hoping to make something out of aluminium. I have recently (and quite successfully) made a set of four overriders (£20), and a set of four outriggers too (£11.50).
Regards, Si
