I'm sorry Head Turner but, as I said, I'm waiting for the design chaps to let me know the work required in fitting this extra. That's the trouble with engineers; they think they're artists and tend to have the "artist's" mentality! They don't understand my job in the real commercial world when I have eager customers banging on the door demanding to be put on the order book!
I'll chivvy them along a bit. Nicely of course.
Cheers
