Triniy NOW assistance please

So.. I had some issues with the stock motor in my Trinity NOW 1/16 truggy (this thing tends to have a few drivetrain issues; once they're all sorted out and it's running, it runs really well though!). So anyways, I decided to get another motor to replace the feigao that runs it now box stock (the thing gets far too hot; I think I temped it at 180F after only about 5 or 10 minutes).

Now, I just noticed that my steering servo is totally gone. I think it may be the gearset, but being that Trinity wants to make my life a pain in the butt, I have NO idea what the specs are on this stupid little servo.

Is there anyone out there that has any idea as to what servo is either A) a direct drop in on this chassis, or B) can I modify the chassis to accept a standard 1/10 scale servo?

Thanks in advance guys. I want to take this rig back to college with me, since it's easy to replace gears in the diffs when they do go out. Plus, I want to see how this new motor runs. I think it's about 200kv less, and has a finned can. Soooo....hopefully it'll hold up better. I'm willing to settle for 160F after a full run! UGH...
