cheers for the response les
think I'll be sticking with the sierra cvh since it's close to the book - I've noticed the correlation between very unique projects being complicated and simple projects being easier to find the info on how to do it i.e. suzuki gsx-r1000 engined roadster opposed to a sierra derivative.
A guy on the locost builder forums pointed out the type 9 = reverse at top left, mt75 = reverse at bottom right, but thanks for that all the same
I'll find the sierra owners club and add it to my favs asap.
No doubt I'll be back here often to pester you wise people for lots of random info
thanks again!
