I have a Mountney steering wheel boss to fit a Sierra column with the hexagon top (not spline)
Unfortunately I've misplaced the horn push in my house move.
£10 plus £3 postage

If it has the indicator cancelling I'll take it.
If i remember right the indicator cancelling was just a small plastic ring the clipped onto column.
The underside of this has a cutout for someting like a pin?

I will need to look at my existing Sierra truck steering wheel I have on at the moment, but I am unfortunately in Munich until Friday night so will
not be able to look until then. If that's a problem I understand chap 
U have first dibs if anyone can confirm boss has cancelling.
Thanks mate 
looks like the boss has the cutout for cancelling but you will need the plastic ring as well. Also top tip, use a bit of blutack to hold the ring in place when you're putting it together
