Today i went to take off my stock 13" steel rims from my new 1990 DX winter car, and put on a set of brand new 14" rims/winter tires but i ran into a problem. All the nuts came lose except for 1...half of the head actually broke right off the nut, and now i cant get anything on to "grab" the remaining part. What do i have to do to get this off now? I don't care about the hubcaps or rims that are currently on the car, so any kind of "butchering" is ok with me. I just need to get my new winters on ASAP! Any help/tips/pointers are appreciated. Thanks!

 

Vice-grips and a hammer? Is there enough of the nut left to grab onto with any tool?
