Mohamad:

At my local auto parts store they sell after market "cruse control"
systems.  These include a magnet which is tied to the drive shaft
(or in the case of a front wheel drive car - a half shaft) using
a long plastic tie wrap.  Also in the kit is an inductive pickup that
mounts to a metal strap using a 1/4" bolt.  The strap can be attached
using a couple of sheet metal screws.  The output is a pulse once per
turn of the shaft.  Needs to be calibrated.

Have Fun,

Brooke
