You realize we are talking about the rear body mounts on the tub not the frame right?
that is the tub portion ...or somebody's version of it. isn't it?
they locked in square nuts to tabs that are just as cheesy and prone to rot or bend. but that looks like the whole rear sill to me and it shows the cover in that last drawing. that should make a whole new TB.
if you cut the head off could you punch the shank up through? the torque has some depth inside and should allow the bolt to go up if the nuts are free.
Apparently on my driver side - it all fell out on its own somewhere along the way while I was driving. Passenger side is just spinning.
I'm going to use a hole saw to do a nice cutout and go from there on the passenger side. Driver side needs totally rebuilt so I picked up a sheetmetal brake and plan to rebuild the ends out of 16 or 18 gauge with all the factory 90 degree bends that give the box it's strength.
Some pics of what is going on inside there and my guide to rebuilding those sections. If anyone has any other actual pics that show details I would love to see them.

Few more panels and you will have a brand new body glued together.
Im guessing open end on those sections goes towards rear, so when its put together, it will be closed off just as factory?
I still have not sealed off my openings, what im thinking to do is use a hole saw to make perfect round holes and use a rubber plug/cap to cover them, just like floor drain holes. This way they are always accessible for what ever reason.
I am not a fan of closed off sections like this, without easy means to ventilate and self clean, its just a matter of time and few offroad trips before rust starts cultivating in there again.
@kincaid.0678 have you checked mounts by cross member?
It is another stupid closed off section where all crap accumulates, and my bolts have rusted in there beyond saving.
I was spraying and torching driver side bolt for entire day till a nut gave way and started sniping inside the clamp. Now i have to drill a hole in the trunk from inside to get it out
