Ahh the old RC10T. My first truck, still the ultimate weapon for Sportsman class racing due to its durability over modern stadium trucks.
It might take some creativity and a couple generic body post kits, but back when I raced my RC10T I was using Traxxas Rustler bodies (specifically Pro-Line's long-since discontinued '99 Chevy Silverado). They're very long and wide compared to bodies made for the RC10T4, XXX-T, etc., so you've got a lot of free play at your disposal to mount it low and level.
