Let the nuts soak in PB Blaster for awhile before attempting. If there is not much rust around the stud, the nuts should give way. Just go at them slowly while carefully watching the nut and stud. If there is much rust, you will see the whole base down there start to twist, ask how I know. With enough PB Blaster and time, you should not have a problem.
Thanks
David
