Maybe there's a trick to this, but I am having one hell of a time getting my swingarm installed in my frame. The stock frame is threaded on one end, unlike the aftermarket frame which utilizes a bolt for the swingarm pin. So if I'm using the right parts, I have two timken bearings and 2 spacers. The problem is that the spacers drop down when I put the swingarm in the frame so I can't push the pin through. If I had an aftermarket frame I could just put another pin in from the other side and use the other pin like a drift, but because it's thread I can't do that. Any tips?
