i dont know what the interior of the brats look like compared to my loyale, but this is what i did... http://www.ultimatesubaru.org/forum/showthread.php?t=103792&highlight=holder
got a slide out cupholder from the junkyard, had to modify the radio bracket and facia, works good. since my amFM radio only has 5 presets, i really only use 2 of them anyways. so it works out well for me.
