I am not sure about the nut situation. You might have to cut it off and replace with a new stud. You might get a pair of needle-nose pliers in there to hold it. There is a little gap under the head of the stud and the top stock rubber spacer. Can you put a large screwdriver in there to pry against the stud enough to give it some friction to get the nut off? <img src="/forums/images/graemlins/confused.gif" alt="" />

I am curious, what 2" spacers are you using?
