cheers - good to know that it just works - its all a bit new to me...

i just swapped my cen clutch over onto the os engine, no probs.

dont know about the shell fitting with the wheels yet, when i offered it up roughly in place it looked like a lot of cutting was required. i dont want to chop that shell up really, so i may well go for a electric stadium truck shell, or a different take on the schlesser body.
