I need to replace my control arms due to my pinion angle and some rear end noise.. I think im gonna go with these here. http://stangsuspension.com/store/comersus_viewitem.asp?idproduct=210 Now I dont see mm selling upper control arms. Just the lowers. I would like to do both but if these will solve my problem I guess I will just do the lowers. Any suggestions and advice will be helpful. Also will I need to get any different bolts or anything for the install? Thanks.
