Due to the GenRight Hi-Fenders, I needed to move various underhood components around. I also had to find room for my OBA components, figure out an air intake, and decide what battery tray I was going to use.
The location of my OBA tank limited my ability to go with either the Spectre filter housing or a Windstar filter housing. I knew I did not want to run an open element. My initial plan was to chop the bottom out of the factory air box, I found another solution that worked well for my application. I was also able to tie my York into my intake so it was filtered by my new filter housing.
The BMC filter housing was adapted with various adapters, elbows, clamps, and silicone sleeves. I also added an Outerwears filter screen to the housing opening. (I'll add the actual parts when I get a chance to look them back up)

The two battery tray options I had were the GenRight tray or the (newly redesigned) Nemesis Industries tray. Placing both under the hood, the height and location of the Nemesis tray allowed me for more room. It also allowed me an attachment point for part of my Switch-Pros. I chopped the inner fender brace off the Nemesis tray and bolted it up to the firewall.

With the space created by the battery tray and the filter housing, I was able to RivNut my fuse box to the inner fender. I also attached my Switch-Pro brain box (with RivNuts) to the fuse box bracket.


I fabricated an aluminum bracket to attach to the top of the battery hold down. This gave me a place to put my Switch-Pro power and ground terminal connections.


The factory driver fender support was modified to place my OBA filters/regulators and locker manifold/solenoids out of the way. This cleared room for other items needing to mount to the inner fender (evap canister, a washer bottle, and horn). This also allowed me to keep the factory overflow tank attached to the radiator shroud.
Apparently I did not take a picture when I was fabricating the new OBA relocation bracket. Hopefully the below photos gives the general idea. I cut the firewall side of the fender support bracket vertically and welded a flat piece of plate to it. I laid out my OBA components and installed RivNuts to attach them to the piece of plate. The fender support was bolted back on the firewall.
The OBA components tucked nicely out of the way in the space between the inner fender and below the brake MC/Booster.
