On the weekend one of the bolts holding my arm rest onto the base bar of my Vision Tech’s snapped off and the rest of the bolt is stuck in there. On top of that the second bolt is just spinning when I loosen it and won’t come out. Any ideas how to fix this ? Or alternatively I was considering just having them welded on permanantly. The arm rests are in the correct position for me and are not adjustable anyway, why not just weld them on ?
