Ignoring the gap as that's not what OP asked, and that most of us find the gap nothing to break the deal, I've confirmed with Nick that nothing needed to be changed to fit the 98 wheel on his car back in the day. No need to change indicator stalks or clock springs etc.

YEAH  nothing else needs to be changed afaik
just thought id throw this in there as i wasnt aware of it until i was about to buy it, was def a deal breaker for me, just didnt want others going through the same situation hence why i mentioned it
 
i certainly didnt like the look of it (gap) when viewing from outside the car into the cockpit.
 
cheers
