Not having ARB boxes in the back quite yet, I had to find another spot to mount my Yaesu FT-8900. It's not a big radio. And under the driver's seat, and inboard of the computer I found a nicely sized cavity. The radio slotted in there perfectly. I threaded the separation cable up through the a pillar panel and under the dash to get to the center console. It's mounted with hook-and-loop. But nevermind that...what a sweet little cranny for installing a radio!
