Yeah, original cars came from AC in England.
Kirkhams use a removeable pedal box. If you do a search on this site for Pedal Box, you'll find some pics on KMS pedal boxes.
I have one but have loaned it to a friend. So I can't take any pics at the moment.
Like Chas says, best to contact Kirkham for the correct parts.
