Hi Pheonix
It has two hoops, they do not look like the usual ones, they are welded together and painted green. There are a few pieces of tubing that have been notched and welded in between the two hoops to keep the gap, there is a single bolt on each side retaining the assembly. There has been another boss added to each side of the tray for the second hoop. Point to note, it does not look like the tidiest job in the world. I am confident that the vehicle has been modified, but by who, and when is the question I guess?
It has been a while since I have looked at the old girl, mainly because it is situated 1600km from my current location, but from recollection, the holes in the back would be consistent with the bench seats.
Another noteworthy point, this vehicle is registered on REMLR under the old owners name: Old Dog, from Cobar.
