Momo steering wheel: 2nd attempt

On the first test drive with the Momo steering wheel, the horn was constantly on - which was quiet annoying! I compared the contact rings between the Momo boss and the original Porsche boss - they were very different!

Momo boss, modified in diameter and with recessed fixation points, relocated hole for ground strap:

 Now it works a treat - and it only honks when I press the button!
