i see that style in the local scrap yard quit a bit ,put one on my winter caddy and it works great, there are on the older cars till the mid ninties,see them on all the makes of cars, they can work off a magnet and pick up off the axel for a diesel or for the gasser off the coil , but can be set up both ways , easy to hook up the probems with them are usually the connetions they get corroded.
