need a little help

[Beef52751]

I'm doing a clutch on a 98 2.5l 2wd. I am trying to get the trans crossmember out and the clips that hold the nuts from spinning broke. Any good suggestions how to get something on them so I can get the bolts out? They are in the part of the frame that is boxed in btw.
Thanks for any help
