just pasang the bar today . so damn hard man .. my left arm nuts already rusted . the right still in good condition . the left arm needs to cut a bit so that the rusted nuts can cut out using wrench. The task will easily done (DIY also can) if both of the nuts are still in good condition . But , if one of the nuts is rusted , dont try to push if it is stuck. Once the nuts is broken inside , it will be more complicated .
