Nice post on the seat gear, however how did we get here from the OP original post?
"91 Olds ToronadoI have a bad ABS sensor on front drivers side wheel. no one seems to have one, none of the major chains nor RockAuto" . I suppose you are saying there may be alternatives to the OEM?

yeah, that'* what i was saying. I might find another model or yr car that will work. sorry about going on a tangent,

sorry it took so long to reply, been very busy.
Good News! I went to the junk yard last weekend and found a sensor identical to mine. It came out of a 4 dr. Saturn. every other car I looked at were completely different. most were in the Hub. I just hope the one I got is still good. It looks good. I'll let you all know when I get it in but it may be a while. I'm doing major work on it and it'* up on jack stands.

haven't had time to go to a dealer.
