Stripped threads on shift coupling Options

[flipb]

I took apart my shift linkage to install a clean transmission housing cover from 914 Rubber. The cone screw at the firewall linkage was already a bit wonky and in putting it all back together, I stripped what was left of the threads from the coupling u-joint.

I have one of these inserts from Auto Atlanta. How do I go about installing it?

1. Do I need to drill out the coupling?
2. What size drill bit?
3. Do I need to get a tap and die or is the insert self-threading?
4. And since the cone screw doesn't have a head, how do I get leverage to put in the insert? Do I need to get a screw of the same pitch? Anybody know what size screw?

(and if there's anybody local to NOVA who wants to help me with this, I am relatively useless on my own. I'll buy you a six-pack.)
