Stering Wheel - removal and horn push

[redduster]

My son has acquired an older, Banjo?, steering wheel for his 70 Minor Murphy. 2 challenges have arisen.
The first is removal of the original 2 spoke wheel, what size is the securing nut and is a thin walled socket the best removal tool if available? If not how else as the gap between the nut and internal wall of boss is tight?
Secondly the horn push electrical arrangement is different. The replacement wheel, 3sets of 4 spokes, has a larger centre push than the existing which is smaller and more compact so the contact arrangement looks different. Is their a way to adapt either the older horn push or the wiring for horn to fit the older wheel arrangement?
Cheers

Hi Charles

The steering wheel nut is 3/4Whitworth but 1,5/16AF is a very good fit and works. ideally you need a box spanner but some sockets fit.

There is a "sticky" at the top of mechanical section which lists most of the spanner/socket sizes.

Many just use a chisel - but keep the nut on until you have freed the wheel on the splines - otherwse it jumps up and smacks you in the face. You would need the earlier horn push arrangement.
