Re: '03 954 swingarm removal
I think it was 23mm wide or something, not sure. When I removed the swingarm, I went to the hardware store and find some nuts and bolts that fit in that hex and then bolted them all together as tight as I could. Placed the stack of nuts/bolts inside the hex, and then a 23mm socket over the end that was sticking out and used it like a big hex key. Use some JB quikweld on the threads and it should stay together pretty well. Will only cost a dollar something for all the parts. Just measure before you get stuff or get a size up and a size down from what you think it may be. I think the largest hex key sears has is 17mm, so I think it'd be too small but measure to be sure.....It was years ago when I last did this.
