 These are the stainless steel inserts or whatever you call it from some rivets that I didn't need these parts for And they just they're a little bit fat for these holes. I'm hoping I can hammer them in permanently Looks like if I taper them a tiny bit Drill these holes a tiny bit bigger so this should fit together Tight fit that's good with a bit of luck. This will fit I drilled through a little bit, so they'll go into the bar Think that's enough All right, those holes are not easy to drill. I got it. That should be some pretty indestructible cranks
