Thanks again - looks like the Odyssey will be the one to go for then as I should be able to mount it on the inner wing being appreciably lighter than an 038 and not too pricey at 97 quid (from the link kindly provided by Steeley)
I was just looking at the numbers but if we're sure it works then I'm prepared to give it a go. I think they look like 6 or 8mm terminal screws
