Newbie needs help!

Just bought this for my daughter, and can't get the rear aligned as the alignment link nuts are rusted tight to the bolts.

Are these special nuts or could I use a nut splitter and replace them with appropriate grade form the auto parts store?

Thanks for helping a newbie!

 

You should be fine with nuts from the parts store. I would include a lock washer just to make sure everything stays tight.

 

Thanks for the assist!
