I"m sorry to be the bearer of bad news, but these , like many other parts , are getting very hard to find , after being discontinued . I see that Walker is starting to make a lot of new remakes of the OEM stuff . You could also PM me for the two that I have listed for sale here, if you'd like ?

I believe that there are threads here about removing them entirely, but the CA. ( or other States ) Smog guys will not pass it without one.
