So sorry, I forgot all about this.
Here are the photos, please ignore the string lines and spirit level. These are only there because I was discussing with a seatbelt company about having belts made to fit the Heritage shells. Rover belts are pretty hard to find and expensive when you can find them. I was trying to get a batch made by a seatbelt specialist because Securon belts are junk quite frankly and I've had enough of replacing mine every three years.
