I have never seen shoulder belts on a convertible. Must be a very rare option. I just assumed that they weren't available. I would like to see the mounting points too.
I posted a whole series of photos of the mounting points but it shows the same as at Kurt S.'s camaros.org site. The seatbelt anchor is bolted to the heavy brace that the convertible frame bolts to, using an existing bolt.
Yes, they are rare, I've only seen a handful.
