i am actually selling some max motorsports control a-arms on ebay right now. i went to put em on my fox and the front wheels stuck out.... my own mistake for purchasing them.
To answer above question...yes, I would get new LCA bolts and nuts while you're there. I was surprised how much my LCA bolts were deteriorated from my 54K 96 Cobra that I never drive in the winter, or rain. I would also get the poly isos. The springs is your choice. I like the stock ride of the new edge Mustangs even though they sit a touch high. The ones that that NO BRAKES has on ebay will work if they are 94-04...he is right, they make the wheels stick out on a fox body.
