Ok thanks. I showed my dad the instructions (he is actually doing this for me, and I am relaying this info to him)

But he has a question. Since I'm trying to do this and modify the ignition ourselves (cutting the end off).. Once we are finished, how do I go abou replacing the pin that we are about to drill out?

Is that a part that I can get without replacing the entire unit?

And also for those of you that have done this, where exactly do you cut? That pic that is labeled "cut here" looks to be about an inch from the end.

Is there something more specific to that process?

Thanks for all your help in advance. This site has become a lifesaver!
