Hey there, I have 2 coarse spline steering wheel bosses for sale.
One looks like it's for a 500 but I can't confirm. The mating surface looks wrong for my 126.
The other looks like it will work with the self cancelling indicators

they both come with a horn button
10 quid for the 500 one and 15 for the 126 one

Cheers!

for the 500?:

and the 126:
