Auxbeam Underhood Mounting

I have a Auxbeam GA80 and I’m looking for underhood mounting options for the relay box. So far I haven’t found much

This looks the most promising but requires spacers for the 4th Gen
Auxbeam PowerTray > 4Runner/ FJ Cruiser/ GX – PowerTrays

I think this could be adapted to work as well, but might be overkill

Amazon.com: Air Compressor Mount for 2005-2009 Toyota 4Runner 4th Gen | V6 | Made in the USA | Rago Fabrication | Compatible with ARB Single & Twin Air Compressor | On-Board Air System : Automotive

I’m not trying to do any fab work if I can avoid it

What have you all done?

 

Slap it on the fuse box was my first thought, but haven't done it yet so just in the planning phases.

This seems like an option for the 5th gen.
