I want to change to a different steering wheel, what is involved?

From RPRWiki

I just replaced the steering wheel on my `87 with a JDM Integra Type R steering wheel made by Momo for Honda. This steering wheel is 350mm and feels great in my hands. Unfortunately this wheel needed some modifications with a hacksaw, a drill and a tap & die set to make it fit onto my car. Honda did not change the splines on the steering column from the mid-80`s until they started installing airbags, so you can swap wheels from any Honda or Acura into your CRX. You may need to make some modifications for clearance to get the 19mm nut that holds the wheel to the steering column to fit, but the splines are all the same. A smaller steering wheel means you will need more muscle to turn the wheel (less leverage). This will make an impact on you if you do a lot of parking. Conversely, a larger diameter wheel will reduce the amount of effort needed to turn the wheel. Your stock steering wheel sticks out from the steering column a certain distance. On my 1st Gen, the steering wheel is relatively flat and does not stick out much at all. On later Hondas, the steering wheel is relatively deeply \"dished.\" Changing your steering wheel`s dish will change the relationship between your hands and the turn signal switch and the lights switch, maybe moving those controls farther away than what you may be comfortable with. Aftermarket steering wheels (Grant on the cheap side, Sparco/Momo on the high end) come as two pieces: the steering wheel itself which is generic to all cars, and the hub that has splines designed for a particular make of car. The steering wheel bolts to the hub; the hub is then bolted to the car. The aftermarket steering wheels come in a variety of depths and widths; generally speaking, the hubs come only in one depth for a make of car. Thus there MAY NOT be a deep Honda hub and a shallow Honda hub to adjust the amount of distance the aftermarket wheel will stick out from the steering column. If you are on a budget, check out your local junkyard for steering wheels, particularly from the 3rd Generation Prelude.
