If You mount a "Cobra barrel boss" to your Ford column and column covers you will have:
1. the steering wheel more far away from the switches
2. a gap between boss and switch covers
3. no cancelation function because the cancelation rib on a Ford boss is spaced on a bigger diameter(~104mm) then the Cobra boss has on its bottom end. Bottom end OD and top OD for the Cobra boss are more or less the same as the AC cover ~ 84mm
If You want to keep the Ford switch gear and covers and as well the distance between steering wheel and stalks than You could:
- Buy a Ford RS steering wheel boss like this:

- check with Moto Lita if the Ford spaced M6 hex socket countersunk head screws/heads will be covered by the original steering wheel badge which has a OD of 84mm
Be aware that the original OEM Cobra steering wheels and bosses have not equally spaced holes, they have a PCD of 62mm on a diagonal line (1 o'clock to 7 o'clock holes) and will not fit to a "normal" equally spaced PCD at standard hubs even if they have the required hole circle diameter.
Below You will see what I described above.
