I had myself been putting this off for the 2 years I have owned my roadster, but lately it has been getting a bit more troublesome, so night before last I printed out the 10 page DIY pdf and dove in.
Surprise !!! Not as hard as you might think !

Couple of hints :
1. the transmission interlock cable is disconnected by pulling DOWN on the 2 release ears, NOT sliding back.
2. it is much easier to get to the ignition electrical plug if you do that AFTER releasing the clamp and rotating the assembly ( front up, back down ).

The most difficult part for me was getting the lock cylinder and locking ring back in after the repair, but I just kept fiddling and it finally went back together.

Total time I spent was about an hour and a half.
