Guys advice needed!

I was given a new moto lita steering wheel for my series 3 Landrover (1981) the boss supplied states it's the correct boss for the year but 2 problems.

1 ) the boss comes with 2 pins for the indicator cancellor yet yet the indicator canceller fitted as standard I believe doesn't have holes for these pins. As such I can't use the indicator auto cancel.

2) the boss actually doesn't really give much clearance from the indicator lever itself so when driving your hand brushes against the stick.

Anybody fitter one of these befor?

All help gratefully received
