Heatshield Mounting, Ideas for improvement anyone? Options

[BeatNavy]

I recently did an engine drop and while I have my teener up in the air I decided to do the back side / underneath cleanup I've been meaning to do for a while -- removing decades old undercoating, looking for rust, generally cleaning up the nastiness that has accumulated (I swear, I'm amazed at just the level of plain dirt that stuck up under everything).

Anyway, to the topic at hand, this effort includes cleaning up the heatshield and the underside of trunk. Had to hacksaw off the mounts to remove the bugger, and I've removed most of the rust and welded in a couple of patches. It won't win any beauty contests, but it'll be miles better than before.

So, how to remount? Do I fabricate/recreate the mounts? But welding really isn't an option in that space. I gather -6's had these bolted from inside the trunk, correct (did they use the same standoff mounts)? Just looking for ideas for relatively easy mounting and removal for cleaning and maintenance, preferably with readily available hardware.
