Thanks again Hudini. I'm just so caught up in making sure car runs right, and debating weather I need the cat or not. I'm going to another volvo mechanic Tuesday with my 02 sensor, bosal catalytic converter,dorman control arms for front, and assess again what is truly needed, maybe that spacer is the way to go, just would like some more qualified eyes on systems. If not nothing, I can return stuff to amazon.

 

Ok, got my control arms changed out, but boy, it seems worse down there now since I also need new tie rod ends and sway bar, soon I hope. Not going to change the cats at this time, sending back my sensor too!
