I know we've been through this before, but where can I buy a new exitor ring, also I think there is another name for it does anyone know, also is it possible to straiten my old one?

 

Also called a tone ring; Ford calls it an "anti-lock speed sensor ring".
About $40 at the Ford dealer.
Ford says they are not suposed to be re-used even if good so trying to straighten a damaged one is probably out of the question.

 

While I have re-used them, I'd never try to straighten one. If it slips off, it could do a LOT of damage; not only inside the axle.
