Putting the spring back into a rear derailleur
 

I took apart my rear der by removing the little c-clip on the dropout bolt. The spring popped out and now I can't get the spring back in b/c it's really difficult to both tension the spring and push the c-clip back in place. I know - it was stupid. Curiosity killed my derailleur. Does anybody have a trick to getting the spring back in?

A couple of suggestions come to mind. Probably the easiest is to find a helper to put the clip back in place as you tension the spring and hold the assembly. Another approach would be to put the derailer body in a vise or some other clamp to hold it steady while you do the reassembly yourself.

I certainly hope someone comes up with better suggestions than these.
