From Raceform this 1/8 onroad specific Pro body post lazer tracer claims to be the only tool that is able to trace the position of the body post, perfectly and precisely, onto the bodyshell in preparation for reaming. Clear or painted, it saves you time and stress and might change how we locate the body post position. Your body will look better than ever, improved consistency between changing bodies and it saves you from messing up your nicely painted body. Especially in 1/8 On-road, the front post is slanted towards the front and even locating the holes on a clear body is challenging due to parallax error. This Tool eliminates all the errors.
