Yeah, I had the same problem with mine. I was confused what was wrong with them myself until I compaired them to my BSD and found that they were slightly different in design. Basically the newer games changed design by making the lower part slightly wider which prevented the arms from being bent easily which is what is likely the issue with yours. When I get home from work I can get you a picture for you to look at and confirm. I actually welded a bead on each of mine to give them the same witdth as the newer design.
