Thanks for that, Jim.
I live in Westleigh (near Pennant Hills) and work in St. Leonards, so you aren't far away by Sydney distances.
I'll give you a call one day and arrange a convenient time to drop by. I won't drive you mad by hanging around all day, but I'm really keen to get a GT40 but need to modify a bit as I'm really pushing the boundaries in height.
Cheers,
Dalton
