Unmodifying a Modified Servo

NOTE: I had originally posted this in the Stamps forum for some reason I can't
fathom, I moved it here.

Original post:
I pretty much already know the answer to this (no) but I'd like to verify with you guys.

I have six continuous rotation servos, but I need a standard servo, or some form of
encoder for a modified servo.

Is there a way to "unmodify" a Parallax (futuba) continuous rotation servo so its back
to a standard servo?

I've seen sites telling how to mod servos, and most of them involve clipping off stop
gears and the like, so I'm assuming no.

Failing that...

Is the encoder part of the servo still intact in the factory modded servos and can I
use that as some kinda wheel encoder for something resembling dead-reckoning?

My robot (who has a cont. rotation servo neck) keeps trying to twist its own head
off [noparse]:([/noparse]

I'm sure he'd appreciate any feedback you guys can offer.

    No and no.

    Look at the wheel encoder sold by Parallax for their BoeBot or buy a standard servo. They're not expensive.
    I'm sure you could make an IR position "stop" that would indicate when the head has reached the end of its
    designed rotation. An IR emitter and IR phototransistor would do the job. There are examples in the Stamps
    in Class tutorials.
