Pick head Brkt, and the last is the top rifle mount. Will fit the driver side with no issues, but they are a pain on the passenger side.
There should be a set of brackets on the side passenger of the tub as well, you will never guess what they were for.
Roof rust like yours is not rare, as well as inside the centre vent, and around the battery box etc.
You could always paint it back to the red, with all the markings, it probably spent more time red than green, and will be waaaay faster.
Be interesting to see if you can unearth the markings on the bonnet, hope it's not too late for wet&dry with plenty of water. As a side note, don't let anyone sit on the either of the bonnets, you will end up a major bumdent.....
