Are you still looking for a roll hoop Rian?
I have the old one out of my 56 when it was dressed up like a street racer siting in my gardening shed. Completely forgot about it until just now.
It is a 3 point cage, goes straight up from the drivers shoulder curved at the top above your head and then goes down to attach on the passenger side. Has a belt bar that connect the 2 sides of the triangle. There is then a bar that attaches from the top of the 'hoop' and runs down and back to the rear passenger side.
Now. I could take a photo but that would necessitate me clearing the shed out...
It is also chrome.
And heavy.
Let me know if it is of any use.
