I just got lucky and someone gave me a new bumper with a grill/brush guard attached to it. I would like to take the guard off the other bumper and put it onto my truck. I have an 89 bronco XLT! im having problems getting the bolts off that are on the bumper. By this i mean the ones that are round on one side on the front of the bumper. When i try to losen it from behind the round part just keeps spinning!!! and it doesnt come out far enough for me to get and kind of wrench behind it either...any ideas? i might end up having to swao the whole bumper, but that calls for reliable friends! help in the whole process is appreciated!
