What went here?

I'm assuming some sort of standoff adapter/bracket for an antenna mount. Was here, but in a few months of searching have only turned a couple of possibilities. Anyone out there have any ideas?

All HMMWVs had those holes in. Would usually have an antenna bracket.

I have the one that was installed when I purchased the vehicle (on the right rear), but have since replaced it with the standoff version. However, I'm stumped as to what could be on the left rear, with all the different system mods that have been "mission dictated". Maybe it's the remnants of a sort of hi-power setup. I used to have a picture saved. Once I can find it again I'll post it.

How did you overcome the fact that that offset mount is meant to be flush with the body and that the helmet top has a lip that extends about 1/2" or so out from the body? did you use spacers?

I trimmed the lip of the helmet top (since it's only fiberglass and I'm considering custom building my own hardtop). There's still a bit that could be reset to allow a better fit as the stand off is at an angle leaning aft. However, that would require a bit more surgery than what time allows at the moment as some of the helmet top mounting hardware is actually in the way.
