That steel support bracket doesn't really do much for the cargo interior trim, you could lose it and maybe orient the ARB pump vertically? Does it care which way it is oriented?
I also didn't recall the panel for the fuel filler being so deep / the subwoofer box being so shallow on that end.
If you haven't put it all back together yet, I'd strong encourage taking the opportunity to do some sound deadening work on the body side wall and wheel tubs. I used a few layers of peel and stick butyl rubber home construction window flashing as a poor man's 'sound mat' and it worked great. Really killed road and tire noise.
I've got a bunch of pictures of that posted here somewhere, I'll try to find / link some of them. The butyle tape is 6-7" wide. I cut it in squares or rectangles so I could readily plaster it on the compound curves of the wheel well and longer strips where I could. I basically covered all the sidewall and floor steel from the 2nd row seats all the way back and it became dead quiet back there.
eta not really good pictures, but they convey the idea. I might have better overall shots in my storage drawers build topic
