For some reason, I cannot post pics in the road racing/auto x section, I've asked several times why and no one will give me an answer as to why or flip the switch to allow it.
Even if I could post pics, you can't see much with the wheel on there. I can probably PM you a pic of everything installed if your interested, let me know.
Essentially when I went to install the wheel on the car, I found that the old wheel's base was around 5 inches in diameter, the Momo hub was like 4 1/2". This left a gap in the column trim viewed from the top that was very visible and not very pleasing to the eye. Additionally, because the plastic housing that holds the switch contacts for cruise and horn had to be removed to install the wheel hub adapter, there was no way to use the horn.
My dad is an HVAC contractor so I went over to his shop and planned to use a piece of sheet metal to cover the hole. I was rooting around in his warehouse and found these ductwork caps of varying diameters.
They are a mushroom looking kind of deal, an open shaft, closed at one end by a flanged end that's at a wider diameter. The flanged end on mine is about 5 1/2 inches. I think the shaft diameter is around 5 inches but I can't get to it to measure, essentially when the wheel is removed, there is a gap in the plastic column trim around the steering shaft. When you get to that point, just measure the diameter and go to Home Depot or the like and find a cap that is close in diameter at the shaft end, because the cap is flanged and wider at the flange, even if your cap shaft diameter is a bit smaller, the flange will cover the difference when you view it.
I got the cap home and found that the shaft of the cap was too long and left the piece sticking too far out of the column, I used some sheet metal sheers to cut the shaft shorter so that the closed (flanged) end could make contact with the to the metal bracket on the steering column that once held the plastic bracket that housed the horn and cc switch contacts to the column. I used a hole saw and cut a hole in the cap a bit wider than the steering shaft diameter. I then made a template and marked the location of the mounting screws for that plastic bracket and then drilled holes in my cap to mount the cap to the column. It was at this point that I realized, I could simply make a hole in the cap and mount the switch contacts to the cap to make the horn work. I carefully cut a square hole for the switch contacts to go through, then drilled a small hole for the mounting screw for the contacts to bolt to the cap. I was able to bolt the switch contacts directly to the cap and when I installed the Momo hub (which has contacts on it for the horn) they made good contact and I had full use of the horn.
Hopefully that helps, if you get in there to look, it will probably make sense. Again, mine is a Fox car and yours an SN95 so some things might be slightly different, you'll have to kind of make it up as you go like I did if stuff varies.
