I almost hate to show this pic as it makes the rear floor look really bad - and that’s *after* I hit it with a flap-disk.  I can see why the rust was leeching through the Durabak now.

Anyway - I’m anal about having cargo secured, so wanted to get some tie-downs behind the rear seat before everything gets painted.  I just welded in some nuts big enough to run a ratchet-strap hook through.  Should be plenty strong enough for the cooler or toolbox that will ride there.
