The problem is that the mount on the handle is too small for the cable I bought from a guy on eBay who swears he sent me the right part. I also bought a replacement handle from him since I manged to break the handle putting the wrong cable on. Whoops. And of course the replacement handle I bought from him doesn't fit into the control because it's too thick at the pivot point. My original was metal and long and his was plastic and short. It's a 2004 A 35 which incidentally, won't idle.
I just want to be able to figure out what part I need so that I can get him to exchange the parts that he told me would fit for ones that actually do.
