Have already looked at the OEM setup, and have a heap of OEM plastic parts including factory servo mounts. Unfortunately they are too wide for this chassis, thinking this used some form of smaller servo. Guess I'll just have to get some smaller form factor servo and rig up a custom mount for it.
Ok, this one is a long shot, but fingers crossed. Been going through all of my RC stuff and found the Kyosho Mini Inferno my friend gave me. It has a KMRC carbon chassis conversion on it and I can't figure out what it used for steering servo mounting. This pic isn't of my actual car, but it is...
