SEL internal spring bars

[DDG]

My daily worn 2004 EXP ll has a lot of slop in the bracelet where the solid end piece pins to the rest of the bracelet, especially on the 6 0'clock end. From what I can determine from other posts here, that first hidden pin is actually a spring bar. But, I can't figure out how to remove it, out other than wait until it finally breaks or wears in two. (It may actually be broken already) If I could shear it somehow, I could replace it. The rest of the bracelet is good, except for the tiny double headed rivet that goes through the flip lock. It's is about worn through too, but I think I can get it replaced locally. I took out all the screw pins and looked at them, and they have some wear too, one has lost about 1/4 of it's diameter. I think I could replace all those, and take up a little slack. Any ideas on the spring bars?
