Query: Doesn't Measure Up

I have a barbell set I bought back in the 80's but the clamps rusted so I needed replacements. Since everyone's gone to 2" Olympic size as an industry standard I searched high and low for these, hoping for the best. They're 1" in the fact that it's the total circumference of the clamp, including the coil. The space between- you know, where'd you'd slide the bar through- is much smaller and doesn't fit either the bar or the dumbbell, and I'm not about to bend them out of shape in an effort to make them fit; I shouldn't have to. Time to return to sender.
