A bonnet?!?!?! At the rate the bloke at Toyshop was unbolting parts as I loaded the cut onto the ute, I'd say I was lucky to get home with much more than a bare block!!
But seriously, there were no panels of any description on the cut, even when I first sighted it. So sorry, can't help you out there I'm afraid
As to the brakes, I am sure some had twin pots though - Celicamad's conversion springs to mind.
