Gotta do it fairly soon. It's actually not required AFAIK by my local track groups, but seems like a damn good idea and also removes another minor inconvenience (the locked steering) when pushing the car around or working on the front end.
Is it really obvious once you pull the steering column stuff apart -- which I've done once before -- or any gotchas/tricks involved?
I will probably replace the ignition switch and key while I'm in there. The keys I got from the PO are in pathetic shape. The original black key has like no teeth...looks more like 90 years old than 30
